Rated 5.0 out of 5.0 by Cottager A delight to use
Faced with sealing all the windows in a new cottage, I bought the gun based on a recommendation of a friend. The gun makes foaming a snap. It gives you total control over the amount of foam dispensed by squeezing the trigger by varying amounts. Let go of the trigger and the foam stops immediately, without any excess like you get with a conventional foam can. It's amazingly simple to run a bead of foam of any size, the control is so precise. You can store the foam on the gun up to 1 month, so if you have half a can left over at the end of the day, it's ready to use later. No more wasted cans. Make sure you follow the instructions for care of the gun - there are good how-to tips on the Dow web site.

Rated 5.0 out of 5.0 by Dave One of the best while at the same time, most frustrating tools I own.
This little gun is amazing and, also, very frustrating to use consistently. When it works, it works well. I sealed an entire sunroom with just two cans (designed to be used with it) and, you can finely tune the bead to dispense as little or, as much as you like. The product availability for it is an issue for those of us living in the sticks (always available online through Home Depot) and the shelf life (as stated by the manufacturer) is time sensitive so, if you do find it in stores, be watchful of the shelf life issue. I cannot imagine using it too, without the cleaner (acetone) that is sold by the same manufacturer.
The reviewer that stated that his gun seized up, is well, right on as far as this gun's tendency to do that. On the other hand, I've always been able to get it to work with a little patience and, to me, it is worth the patience required in maintaining it because as I say, when it does work, it works REALLY well.
Be prepared to spend some time with it if you purchase it. Also, watch the videos on Youtube. The biggest advantage of using this gun over the smaller cans is the ability to use it and walk away from it without doing a thing to it for a month or so. Which actually works best, in my applications. To leave the gun attached to the product in the cans. Taking it apart after every use and cleaning it is costly and time consuming and, the smallest amount of product left in it, causes it to lock up...

Rated 2.0 out of 5.0 by Delta88 Is this really what the 'professionals' use?
Bought the GREAT STUFF PRO 15 Foam Dispensing Gun for the construction of my house. Most expensive of the guns available, but experience shows that it is not good policy to cut costs on tools.
Used it for the range of Dow Pro products: foam, low expansion foam, and, wall and floor glue. Very satisfied with all of these products and the performance of the gun, until about nine months of use when the gun stopped working: needle valve seized in the barrel. Could not disassemble. The junk pile.
Bought two of the model 14 (each around 1/3 of the cost of the made in Switzerland model 15). Have had occasional problems but easy to disassemble and clean. No obvious difference in performance between the 15 and 14.
Experience with the products is that it is a waste of time and money to remove the can after use and clean the gun with the cleaning canister. Typically the seal on the removed can leaks (pour acetone - the solvent in the cleaning canister into the seal well and watch for bubbles) so that on reconnection, zero. Secondly, the cleaning fluid does not remove all of the product, leaving a hard residue in the can seal area and the gun that blocks subsequent operation. Better to leave the can connected and every month or so dispense a small amount through the gun. Am buying a third to have a gun for each product.
Following the instructions for shaking the can prior to use, and during use, resulted in tennis elbow. Bought a paint can shaker.
