It is difficult to imagine how this tool could disappoint. I suppose it could be off, but I doubt it. That being said: it works beautifully. Small, simple, and idiot proof. And I know 'csuse I are one.
This little gauge works great, is easy to use with one hand while you hold and adjust the router with the other, and then hangs neatly on the side of the table or workbench on a hook along with the wrenches for changing router bits. Can't ask for much more. If you need accuracy to, say, 1/64", you should probably spend the money for a digital standing gauge. Otherwise, this little thing is a godsend.
This has proven to be a real advantage for me. It is so much easy to set the router depths using this gauge than the old way I did it with a tale measure. I use it often and believe it gives good value for the money.
This is a handy gauge to set router bit depth. Setting some depths (1.4" for example) gives you only two flat points way out to the side, making it a bit hard to use, but much easier than measuring with a ruler.
I really like this depth gauge. Works great for me. Small, easy to hang anywhere. I've found it to be accurate and simple. Impulse buy that proves useful. Far easier, for me, than trying to set a combination square or use something else.
