Review: Heavy built - I bought this to do drive way seems standing up because bending over hurts the back , used it today and it took a little getting used to because your far enough away from the seem it was hard to get good depth perception and the right angle to see how much you were putting in the crack, I had purchased the rollers extra for the gun , I found that it raised it to high from the seem and didn’t have good control and to jerky, so I put on the piece that came with gun for 2x4 and it worked way better because it dragged on concrete and got me closer and gave more control, this is a very good idea, would buy again.

### ⭐⭐⭐⭐⭐ Good gun
*by A***W on 17 October 2024*

Bought this to reach some areas in the eaves of my house off of a scaffold. It did a good job. For what it is, it's pricey, but it is a quality product that will last a lifetime for sure. You do have to buy the adapter if you want to use standard 10oz caulk tubes, which is annoying. For the price I feel like that should be included in the package. Just something to be aware of.
