Rated 4.7 out of 5 by 6 reviewers.
Rated 5.0 out of 5.0 by very good, performs as well as I hoped I have never used a powered caulking gun before and this one has performed better than expected. We are using the gun to apply adhesive to structural insulated panels. This gun has increased our assembly speed and reduced the waste of material. The gun has a "drawback" feature that stops the flow of adhesive almost immediately upon release of the trigger. The clean-up of the gun is quick and easy. Replacing spent sausage tubes takes very little time and produces less trash at the job site. If there is a down side, we have gone through six tips on this project. They seem to break at their base if the user leans a little too hard on them. They cost about $6.50 each and are available only at a Milwaukee repair shop. I guess the real downside is Home Depot. They need to stock support items at their stores if they want to sell them. I guess the only thing that knocks down my rating is lack of support by Home Depot. November 23, 2014

Rated 5.0 out of 5.0 by perfect to do the job the right way I'm a auto glass technician and this caulking gun is one of the best to installed urethane October 28, 2014
Rated 5.0 out of 5.0 by milwaukee tools Another great dependable tool from Milwaukee.... Makes my jobs so much easier September 23, 2014
Rated 4.0 out of 5.0 by Problem removing sausage I install auto glass and have used the 14.4 version for several years and is why I stayed with Milwaukee. This gun has great power, battery, and accuracy. The only problem I can find is that the sausage consistently wraps around the end of the plunger and is very difficult to remove. I would give 5 stars if this wasn't the case! January 3, 2013
