Foaming Gun, MANGZ Hand Foam Caulking Gun, PU Expanding Dispensing Foam Spray Gun Application Applicator for Caulking, Filling, Sealing

So far, so good. Worked as expected and much cheaper than most options. Its hard to keep these guns clean over several uses, but at this price, i can afford to replace them more easily.Just a hint... none of these guns hold up if you dont clean them. They make cleaner, but it only works while the foam is still uncured.

Gun is well made. Came with 2 tips. Have not used yet, but will soon, and will update then.Update: 10/1/2020Have used this foam gun on several projects. It works just as good as the day I got it in the mail. As long as you spray foam cleaner (sold separatly) through it right after using it, the gun will last a long time. The foam cleaner is sold at ace, lowes, home depot, just don't put any foam through the gun until you have the cleaner in hand or the gun will be one time use.

This is the second one of these I've ordered. First one held up pretty well, but o-rings quit sealing, so cans could leak or off-gas, but still ran 1/2 dozen or more cans through it. Good control, and easy to clean overall with a can of the gun cleaner. Allows you to use the foam as needed, and not just waste it. Well worth the investment compared to the regular old cans you typically can only get a single use out of.

This took the frustration out of spray foam. Yes, the bigger cans cost more, but at least they won’t be lost to a crappy spray nozzle. This thing salvages every drop and makes application unmessy and manageable.

Seem sturdy and well built enough, until you look at the details. I'm a stickler for certain things, and very accident prone, so I immediately spotted the shotty cast job on the threading for the can. When I tell you the spurs were sharp, they were KNIFE SHARP. Deburred and fixed the threads, and the very first can I attached wouldn't fit properly. There is no way to correct this once the can is started because it punctures the seal and the pressure keeps enough resistance that it's just impossible. I tried everything to tool it off or remove by hand and every attempt failed. Even without successfully running foam through the gun, though, the parts of it where the foam was leaking from it was obvious weren't just from a misalignment malfunction. Each crease along the shaft where the parts connect had foam slowly leaking out. What a waste of time and money.

I didn’t want to spend more than double for the name brand one. And the low end name brand gun has nothing but horrible reviews. I took a gamble on this one and I am happy I did. No issues. Works just like you would expect.Update: instructions on the can of foam say to leave it connected to the gun if not emptied completely. So after leaving this gun connected to a half empty can for about 2 months, I was very happy to find it working perfectly still! I did make sure to spray the tip with gun cleaner after each use. Very happy with this purchase.

Like many people, the low price of this foam gun enticed me to buy it. Worked great at first - although the handle is definitely made for small hands and not average size hands. After a few weeks, the valve would never open - allowing foam to flow. It stuck in the closed position - until I finally squeezed the trigger hard enough to break things loose. Then I lost half a can of foam (and made a big mess) before I could finally turn off the valve with pliers. I'm ordering another model now - along with a fresh can of foam since my current can emptied prematurely. I recommend a better quality model.

Between this and a two foot spray gun I bought on Amazon, these are two of my most useful tools that have also saved a lot of money over the individual bottles with the straws. It provides less waste, more control, is easier to clean, and easier to reuse. Make sure to get spray gun cleaner (acetone.) Also, some petroleum jelly around the gun threads makes it easier to remove as well. At first I didn’t want to spend any money on a spray gun, but after using this I feel like a fool for not purchasing one sooner. I have no comparison to the name brand spray guns, but I also have no complaints about this. Without having used the others, I’d say just save your money and pick up one of these instead.
