18V ONE+™ POWER CAULK & ADHESIVE GUN is rated 3.8 out of 5 by 4.
Rated 4 out of 5 by from Mix bag I’m not sure what to think of this. I feel like it waste a lot of caulk. The problem with this tool is that it ejects too much caulk and the caulk gun can be a little too big to fit everywhere. Plus when I’m done it continues to squirt some more. I will most likely only use this on larger projects. Oh, I find it very useful to do larger tubes since those requires more strength, and with this, it works like a breeze.

Rated 5 out of 5 by from Awesome power caulk gun I use this on a regular basis to run urethane (the 'caulk' that glues car windshields in), and fire caulk, both of which are very 'heavy' adhesives - they require a lot of effort with a hand caulk gun. Said 'high effort' took a toll on my wrist after a couple of decades.... You aren't going to run the caulk or glue any faster with this - but, it does help reduce the wear & tear on the body.

Rated 1 out of 5 by from I can't give a zero as it isn't available No matter what medium I used the tubes all broke open...I even wrapped tubes in duct tape and they leaked... It got to the point where I couldn't clean the gun up enough to take back, just tossed it so someone else wouldn't be disappointed and frustrated.
