Rated 4.6 out of 5 by 17 reviewers.
Rated 5.0 out of 5.0 by Works GREAT This caulk gun works great. I have used this for caulking, and liquid nails. Easy to use, variable speed and does not drip or keep pushing out caulk after you let off the trigger. If you are looking for a battery powered caulk gun I highly recommend this one. I have to admit that I am predacious to Milwaukee tools but for good reason. I think they are the best on the market. December 30, 2015
Rated 5.0 out of 5.0 by Unbelievable... Excellent product. Works better than I thought it would. Highly recommended to anyone who uses a caulking gun. Used it to seal my driveway, with the thick sealant. Used it with Self-Leveling concrete sealant in my basement. Worked great with all those applications. December 29, 2015
Rated 5.0 out of 5.0 by Makes Caulking an Easier and Quicker Job Like another reviewer said, for us older fellows, squeezing the trigger on this tool is much easier than using a manual caulking gun (particularly if you are using polyurethane caulk). In addition, the speed of application using this tool is easily several times that of a manual gun. The ram speed control knob is marked 1 to 6 but has 20 actual detent settings which makes it easy to get a flow rate that accommodates your travel speed and the gap you are filling. As stated, the ram reverses when the trigger is released so that there is no dribble. It reverses about 1/8”. My only minor complaint is that when using, for instance, the 1.5 setting (which met my recent conditions) it takes about 10 seconds for the ram to advance to where it puts out caulk. However, with practice, if you watch the gap ahead more carefully, you will probably release the trigger less often. I am just a homeowner who likes to do his own maintenance and remodeling and enjoys tools that work well. I would think this tool would pay for itself quickly when used by a professional. One of the reasons I bought this tool was to use it to reach an area on my house exterior which could not be easily from the scaffold. I fabricated an caulking gun clamp which attached to a pipe extension which is pictured. Pulling the rope operated the trigger. It was reasonably successful. . August 2, 2015
Rated 4.0 out of 5.0 by Very handy at times A little delay to start the caulking. But, very handy tool. Especially in the cold when its hard to use traditional guns. December 22, 2015
Rated 5.0 out of 5.0 by 12Volt Success Pumps high viscosity urethane with ease.The gun is not too heavy, yet has a quality feel. It can do the job as good as an 18-volt unit. December 15, 2015
Rated 2.0 out of 5.0 by Milwuakee caulk gun A decent product, seems very sensitive to temperature December 8, 2015
Rated 5.0 out of 5.0 by Easy to use once you get used to it. This gun is easy to use once you get used to it. Just be ready to move it when it starts coming out and start out on low speed. I love it. It is a definite hand saver when doing a lot of sealing like I did to all my windows and things on my rv it is a time saver too. It has same great Milwaukee quality as all my other tools by them.

Rated 4.0 out of 5.0 by Has it's place, Will take getting used to. I'm over 50 and a professional contractor. My right forearm, that has gunned thousands of tubes of caulk, is injured from overuse. I decided to try this gun on a big paint job. It is well made and has plenty of power but lacks the finesse of a manual. It is also quite heavy for a full day job. The biggest problems I am having is that when the trigger is released, it goes into the reverse function to stop the flow. It then takes several seconds to get another flow of caulk. This gets tiresome. Also, the flow seems to start slow, then get higher and higher so you have to move to its' speed not your own, starting slow and moving faster. I need to experiment with cutting the tube smaller than I usually do, different speed settings, etc. Right now, I think this gun will be best for large cracks and long cracks that can be walked and caulked because the trigger can be left down through the entire operation. I use Z-Pro Acu-vac manual guns. (the best gun ever made) I will not get rid of them but will try to use the M 12 as much as I can. Who knows, I might learn the intricacies of this gun and how best to use it. Another negative is that it doesn't have a cutter. You have to use a snip or knife which is kind of a pain. I think if the manufacturer added a variable speed trigger instead of the knob and switch it would be a lot more user friendly. August 18, 2014
