The tool is very accurate, feels good in the hand during use, and leaves a nice clean look where the pin went in. The instructions are excellent.

Works great. Nail depth easy to set. Worth the money compared to cheaper nailers I’ve used.

Best pin nailed I have had
I have used many pins of different sizes the last few weeks. Not one misfire. Had a low cost pin nailer that had a habit of not setting the pins. Not a problem with this Grex.

Woodworking Experience:
Everything it was cracked up to be!
I have been very pleased with my new Grex P635. I love the way the pins are almost invisible after insertion. No need to fill any holes. And the long pins go in as easily as the short ones, even into oak and maple. I will recommend this to anyone who is interested in an excellent tool. I'm looking for ways I can use it!

Unbelievably good
We cannot even buy these in Australia, so I paid the postage and was really happy. The holes left are almost invisible. Buying through Rockler was easy, I think I might be buying all my high end tools for them.

A truly excellent product
Beautifully made, completely lives up to the company's claims, it will get a lot of work. Was able to fix glazing bars on 100mm x 100 mm glass panes, with ease, (dumb design I know but it looked good).

The Grex is everything the reviews...
The Grex is everything the reviews say about it. I know better than to buy inferior tools and the low cost pin nailer I purchased was unacceptable. The Grex is a quality product that does what you expect. Hope I remember this the next time I make a purchase.
