1) Submitted by Mike K Taylor, from Columbia, MO on 1/23/2011 Customer Rating: I got this depth gauge to set my table saw blade and fence parallel to my miter gauge slot. I couldn't be more satisfied. It worked great!

2) Submitted by Cary Sanderson, from Billings, MONTANA on 1/23/2011 Customer Rating: It was exactly what I expected and has performed very well. It only took moments to figure out how use it. I have already recommended it to several friends.

3) Submitted by Steve, from Silsbee, TEXAS on 1/23/2011 Customer Rating: This is a very good tool and it is easy to use. It is very accurate and it has many uses.

4) Submitted by Gerry Grassman, from Camp Hill, PA on 1/12/2011 Customer Rating: Just the item I needed for my workshop. Another quality product at a reasonable price. Always a pleasure to deal with Rockler.

5) Submitted by Denny Arndt, from Mohawk 13407, NY on 1/12/2011 Customer Rating: This guage is defendantly a keeper.My dial indicator works ok,but it dosen't convert to fractions when you need it.Perfect when i'm useing my box joint jig.

6) Submitted by Larry, from Ellsworth, ME on 1/11/2011 Customer Rating: It has separate posts that screw into the main post. I'm sure I not clear! In any event, the extra posts can be screwed into the main post extending the depth you are able to measure. This makes the tool not overly long yet able to measure deep into a hole. By main post, I mean the one you see in the photo on this web page.

7) Submitted by Lloyd Jones, from Creston, IA on 1/10/2011 Customer Rating: I bought this to set my table saw and routers. I've not used it much but it does what I expected it to do. It is very accurate, that is what I needed. I give it a thumbs up.

8) Submitted by Steve Bowers, from Ewing, MO on 1/10/2011 Customer Rating: Nice addition to my tool bin easy to use, easy to read additional stems are a plus, ordering from Rockler is fast and easy keep up the good work

9) Submitted by Ray, from Savannah, GA on 1/10/2011 Customer Rating: The gauge is very accurate. I compared it to a precision depth gauge and was very surprised at the level of accuracy. The best part is the conversion to fractional readings without going through the longhand math exercises.

10) Submitted by Jeff Badman, from Huntington Woods, MI on 1/10/2011 Customer Rating: Purchased the product online under the impression the tool body was mainly of a cast aluminum. I was surprised to see it is chiefly plastic. No comment on durability because it hasn't been used enough. The design concept is good, I checked it's accuracy against known exact dimensions and found it within 0.0003" in 5 accuracy trials. I would expect it to maintain this level of tolerance with repeated use. As a fussy woodworker, I appreciate having machine shop accuracy, my career was in mechanical engineering. It's scope of use is likely wide, as an immediate example this tool would be a great asset in measuring lateral end plays in shafts, or fine tuning blade height on jointers, and setting a parallel relationships of tablesaw blades and miter slots.

11) Submitted by Kenneth Cramer, from North Tonawanda, NY on 1/10/2011 Customer Rating: Very nicely constructed, easy to use and accurate. Was pleased to get it at a discount/w free shipping will be looking into the bevel gauge next.

12) Submitted by Jorge Sosa, from Cordoba, CORDOBA on 7/29/2011 Customer Rating: Snap Depth Gauge is a quick, easy, exact, practical, and very good auxiliary tool for joint tests, tune-up electric tools, and others. I’m satisfied with your purchase. Thanks

13) Submitted by Jack Calabrase, from Pentwater, MI on 1/10/2011 Customer Rating: For the price one can't go wrong. Sure it's plastic, but it works well and is accurate too. I do handle it with caution though.

14) Submitted by Albert Pettina, from Philipsburg, PA on 1/10/2011 Customer Rating: Great addition to my work shop. Quick and easy way to measure board thickness. Easy to adapt to measure blade and router bit height I bought it on sale, what a great buy.

15) Submitted by Alan Falk, from Raleigh, NC on 1/10/2011 Customer Rating: I like the inches/mm/fractions options, and may have to replace some of my other digital calipers to get that lovely third feature, and I don't really mind the plastic parts... the gauge seems to work very nicely. but I'm a bit dismayed by the inclusion of the two "extensions" to the measuring rod. if you add either of the additional ones, "zero" sure as heck isn't when you push the gauge flat to a reference surface, because you can only do that with the original stick in place. with extensions, the sensor won't go down to flush with the "zero base." Maybe some additional directions on how to measure a hole deeper than the original probe would be useful, if it's at all possible... or help me... what did i miss here?

16) Submitted by Phil, from Payson, AZ on 1/10/2011 Customer Rating: I haven't had this depth gauge very long, but it seems to work flawlessly. In spite of the plastic parts, it seems to work smoothly, and be plenty sturdy for it's designed uses. I don't have the equipment to test the calibration, but it seems to be very accurate, best I can tell. I'm sure it will last a long time if I don't throw it into the bottom of a toolbox and toss other tools on top of it.

17) Submitted by Gary Albright, from Juniata, NE. on 1/10/2011 Customer Rating: Am very pleased with the accuracy of this ! A great buy ! Would order again !

18) Submitted by William Berry, from Northville, MICHIGAN on 1/10/2011 Customer Rating: I am a retired toolmaker who is comfortable working with decimals & milimeters. I find the snap gauge easy to work with and accurate. If only the rest of my equipment were this nice.

19) Submitted by Larry Colley, from EL PASO, TX on 1/10/2011 Customer Rating: I have checked repeatability and it is excellent. I am currently fabricating an aux. base for use on my table saw and router table to set tool height for shallow cuts.

20) Submitted by C.E. Martin, from Conway, SC on 1/10/2011 Customer Rating: The gauge is designed to reset itself so that a fraction of an inch shows on the display instead of 0. Awkward at best.

21) Submitted by Steve from MA. on 1/10/2011 Customer Rating: Works fine, does what I need it to do. Great price. One for myself and the second made a fine gift for a friend for christmas. Sale price "rocked" Rockler.

22) Submitted by Barry, from Wilson, NC on 1/10/2011 Customer Rating: Well worth the low price. Even came with an extra battery and extensions for deeper measurements. Simple to use, easy to zero and has mm and US conversion button.

23) Submitted by Rodger, from Leawood, KS on 1/10/2011 Customer Rating: I've not had any occasion to use it as yet, but I've played with it enough to know that it does a very remarkably accurate job of defining the depth and displaying that information in usable form, whether we're talking metric, inches in fractions or inches in hundredths. Service was great and price was even better.

24) Submitted by Andy Pensavalle, from Bullhead City, AZ on 1/10/2011 Customer Rating: A great gadget. I'm really happy I made the purchase. The only reason I did not give it an excelletn rating is because the buttons used to turn on and take advantage of the options are a little small.

25) Submitted by Philip, from Johnstown, PA on 1/10/2011 Customer Rating: This is a great for the price and the quality of the tool. Real handy to use and is very user friendly. Much better than using a tape or ruller to get a depth and more accurate. I would recommend this for any shop big or small.

26) Submitted by k olson, from green bay, WI on 1/10/2011 Customer Rating: very dissappointed because it is mostly plastic. Makes you wonder what's on the inside. Hope I don't drop it. The picture looks better than it is. The only plus was it was cheap.

27) Submitted by Richard Perry, from Houston, TEXAS on 1/10/2011 Customer Rating: I like the new Snap Depth Gauge. I used it the first day I had it to verify the height of my router bit when changing over my stiles and rail cutting heads. It is small and light weight, I can hang it up on my pegboard to easily find it. And when I am using my CNC router I can quickly check the depths of the bit passes to be certian thay they are cutting correctly.

28) Submitted by Ralph Bowles, from Georgetown, TX on 1/10/2011 Customer Rating: Well worth the price

29) Submitted by michele delle fave, from warwick, RI on 1/13/2011 Customer Rating: The device is very accurate, but it would be nice if the lock button locked the shaft in place rather than just the number.

30) Submitted by Peter on 1/10/2011 Customer Rating: It is good. It could be better. There are two issues beyond the quality of materials that I can think of. First, the probe is too fat for some precision work. Second, use of the hold button can disturb the readings. So it should hold automatically for 2 seconds or something.

31) Submitted by Nelson, from Columbus, OHIO on 1/10/2011 Customer Rating: Like others, I bought the gauge because of the sale price and it looked useful. I was surprised to see the magnetic base connector on the back, making it much more useful than I expected. I am pleasantly surprised and very pleased.

32) Submitted by Mark, from Spring Park, MN on 1/10/2011 Customer Rating: I have several boxes full of high end machinist tools so I understand the wisdom of good tools. If you were going to use this everyday in an oily machinist environment it probably wouldn't hold up. However, for occasional use in a woodshop, it's a homerun. I'm extemely happy with it. It simply works well, has good repeatability, is easy to use, and is a great value.

33) Submitted by Ron , from Manchester, KY on 12/29/2010 Customer Rating: I bought this tool because it was rather inexpensive and I figured if it didn't work well, I hadn't lost much. As it turns out I am very satisfied with the product. How long will it last, we will see.

34) Submitted by Saul, from Chesterfield, MO on 12/24/2010 Customer Rating: Solidly made...some metal parts, some plastic parts. Excellent reproducibility of measurement on rezeroing and remeasuring. Reads out in mm, inches, and fractional inch. A really nice addition to my shop for quick measure of board thickness when planing or setting up material for CNC machining.

35) Submitted by Rick Melpignano, from Bellingham, MA on 12/20/2010 Customer Rating: A very useful tool that I've used on many occasions. The digital readouts are much more accurate than the mechanical depth tools I've used in the past. It may be light weight, but it's solid and definitely worth the reasonable price.

36) Submitted by Jeremy, from Greenwood, IN on 12/13/2010 Customer Rating: Good gauge for the price. The true test is going to be how long it last. It is made of plastic & does not seem to be constructed vary well. But like I said for the price it is a nice addition to my shop.

37) Submitted by Joe from KS on 12/29/2010 Customer Rating: Got this in the mail today, and very disappointed. Mostly plastic. Have not used it yet, sure glad I did not pay regular price.

38) Submitted by Robert Caldwell, from The Dalles, OR on 1/16/2011 Customer Rating: The one I purchased does not work and not worth the cost of returning returning it.

39) Submitted by Alan Grupe, from Rochester, WA on 2/5/2011 Customer Rating: Works slick UNLESS an extension is needed. The gauge cannot be zeroed with an added extension. To use with an extension, first zero the gauge without the extension! remove the end cap! add the extension! replace the end cap! take the measurement! add the length of the extension! hope the zero set was not disturbed in the process. Cumbersome at best. Unless I need the accuracy of the gauge, I'll stick with a dowel/rule for holes deeper than 1 3/16".

40) Submitted by J Jones, from Caldwell, ID on 11/13/2012 Customer Rating: Worked right out of the box. Set it aside for a month and when I went to use it, I figured I had a bad battery. Changed the battery out and no go.

41) Submitted by Rob Haberkorn, from San Bernardino, CA on 8/8/2010 Customer Rating: It's a good product. I use fractional readings most of the time, but I can when a reading in mm would be needed.
