Rated 3.8 out of 5 by 30 reviewers.
Rated 4.0 out of 5.0 by Good for DIYer Good overall product The cutter worked fine, but required more force to cut than I expected. I've only used it so far with 5 tubes and it probably is good for several more, so I'd recommend for a DIYer, but if I used it every day as a pro, I'd pay the extra $10 to get a better one.

Rated 1.0 out of 5.0 by Broke dispensing on the second tube It broke before two tubes of construction adhesive were emptied through it. The little metal lever that grabs the rod and pushes it through the tube, broke in half, and fell out. I suppose that when I saw one of these models new at the store, missing that same piece, it should have tipped me off that this was a piece of junk. May 10, 2014
Rated 1.0 out of 5.0 by Better have strong hands! I bought this for use with typical construction adhesive and it was almost worthless! This gun is for the larger tubes of materials but trust me if you don't have huge hands it doesn't have enough leverage in the mechanism to push anything with any sort of viscosity through the tube. As this is the only large gun home depot offers, you'll really be stuck if you buy the more economical larger tubes of anything and expect to use them in this gun. My advice is stick to the smaller tubes unless you buy a better gun somewhere else or you have gigantic hands and a gorilla grip! April 3, 2012
Rated 5.0 out of 5.0 by large caulk gun Large gun is needed for most glue jobs so that you are not stopping to change to new glue supply. November 4, 2014
Rated 5.0 out of 5.0 by Works as intended Needed and inexpensive tool to install a subfloor and it worked perfectly. February 3, 2015
Rated 1.0 out of 5.0 by Ehh.. Terrible build quality. Spout cutter bent and dug into the plastic handle. I bent it back out and it squeezes the caulk out. My advice is buy a pocket knife with this caulk gun so you can cut the tips off. January 27, 2015
Rated 5.0 out of 5.0 by Time saver I am a DIYer and a friend recommended this for a floor I was putting down. I am so glad I did not use my smaller gun. I was able to lay down a lot of glue quickly. I would definitely recommend this product. December 30, 2014
Rated 5.0 out of 5.0 by Big Guns If you have a big job and want to save time by not having to keep changing the glue in your gun frequently . This gun will help conquer that! December 17, 2014
