Rated 2.0 out of 5.0 by Extra Drip Caulk Gun I'm not overly impressed with this gun. I'm a professional contractor and do lots of caulking, and I actually prefer my old $6 HDX drip-less gun to this one. This one is certainly better quality and more comfortable to use, the rotating barrel is nice, but the moment you stop applying a bead it vomits caulking all over the place. Takes both hands to retract the pushrod, so you end up wasting a lot of time and caulk, and generally making a mess all over the client's house. It does lay a very smooth bead, but the mess factor is a real downer. And for some reason they put the seal puncturing rod in the most inconvenient and awkward place possible. January 3, 2015
Rated 5.0 out of 5.0 by Tough caulk gun I should have upgraded caulk guns a long time ago. For years I've been repeatedly replacing caulk guns after they've failed on me. Usually it's the handle that bends, making it impossible to create any pressure in the tube. sometimes it's the ratchet mechanism that starts slipping, to much the same effect. While looking for another replacement, I saw this one hidden up on the top shelf. It feels very sturdy. I don't think my hand could create enough force to bend the handle if I tried. I've only used it for one job so far, and it worked great. Since it doesn't flex as I squeeze it, I feel much more control over the flow of material out of the tube. I think this will last me a very long time. September 21, 2015
Rated 5.0 out of 5.0 by Dual purpose caulking gun Ok, not the intended use, but makes one heck of a clamping fixture with a little modification. These clamps are the bomb! As a caulking gun, they are very reliable and can stand abuse and constant use. They do continue to push caulk even after pressure is relieved if you are doing sensitive stuff...other than that, they are great! As an added bonus, if you save the other parts, can still be used as a caulking gun! December 24, 2014
Rated 5.0 out of 5.0 by Soooo much better than any caulk gun I've used My entire life, I've hated caulk guns. As a woman, my hands are smaller and less strong than guy's are - and caulking anything was a pain. I was contemplating a large caulking project and looking in the reviews - and you will simply be amazed at the power of this gun. I was using both caulk and liquid nails, and it came out like warm butter - easy as pie. I will now proceed with my project and will probably be able to finish in a single day, because my hands won't hurt at all. Thanks for the other reviews, very helpful. Spending $14 on a caulk gun was so worth it. August 31, 2011
Rated 5.0 out of 5.0 by Works Perfectly Love it! No complaints! I would definitely recommend it to someone. September 15, 2015
Rated 5.0 out of 5.0 by Worth Every Penny If there's any chance you'll use a caulk gun more than once, or for more than one tube of goo, this is worth the extra money. I just finished a project using 6 tubes of construction adhesive. A friend helped and brought this model caulk gun. After 1 tube with my old gun, we finished the remainder of the project using only this one. Here's why: 1. Tip Cutter - so much handier than a razor knife 2. Tube Punch - easier to keep track of than a nail 3. Thrust Ratio - this should have been number 1 on the list. My el-cheapo caulk gun had only a 3:1 thrust ratio and this gun is almost 3 times that. Less squeezes of the handle to get the goo out of the gun. 4. Longer Handle - provides more torque so it takes less grip strength to squeeze the handle 5. Ergonomic Shaped Handle - I never thought that the flat shaped handle on my old gun was uncomfortable, but the shape of the handle on this gun with places for each finger sure did feel better during use Now that I've checked these are in stock at my local Home Depot, I'm on my way to get one today!

Rated 1.0 out of 5.0 by high cost product priced higher compared to similar caulk guns from other stores August 11, 2015
Rated 5.0 out of 5.0 by Short n sweet I won't go into an incredibly long, technical review of this product, but I'll simply say that I've broken 3 of the standard duty Stanley caulk guns, either by bending the rod holding clip, warping the handles, or seperating the welded tube from the handle (all of which came from trying to force sealant through a clogged tip), but this one has held up to anything I've done thus far. It is substanstially built and as solid as I've seen one. Hold a standard duty then this one and you'll gladly pay the extra money. Great value. May 13, 2013
