Luft Professional Expanding Foam Spray Gun (1 Insulation Gun + 9 Extenders) PU Insulating Applicator Heavy Duty Metal Body Dispensing Foam Gun Suitable for Caulking, Filling, Sealing

There is one very simple feature of these foam guns that makes them superior to anything else I've used: the manual ball valve on the can connection. Most such guns use a spring-loaded ball valve that gets caked up with foam and will not properly seal after extended use. So you go to change the can and your gun starts spraying foam back at you through the can connection. But here, the balls rotate in place using an external lever. Problem solved. I bought a second package just to make sure I'd have extras in case these went out of production.

The coating on it is nonstick. Fantastically easy to clean. The tip screws off, the adjuster for flow is very wide range and adjustable. It did need a better set of instructions especially how to depressurization and to clean but I was able to more of less figure it out.

These always clog at some point and cleaners do not work. I will always buy cheap versions of these and dispose of them as needed.

I like them alot,especially with the valve on the side.I had the more expensive one from the big box store and it didn't last long

Totally worth the buy !

I was really surprised to find that these seem to work as well as the Great Stuff gun, which I have two of. They also include a valve at the can connection which is really nice for installing and removing cans (I have had some cans leak even though the gun didn't and would have rather not have had the product fill the gun until I knew the connection was secure). I haven't tried the attachments honestly they probably suck like all the rest and shoot off under pressure making a big mess.

It actually works really well if you take this one piece of advice. Don't follow the instructions they have listed on the product page (or if they actually included instructions). Follow the instructions on the can of foam. Open the valve at the top where the foam can screws on. Pull the trigger and point it into a garbage bag. While keeping the trigger squeezed, screw on the can as quickly as you can. Once fully screwed down, release the trigger.If you do everything perfectly, you won't get any mess where the can screws on and you may not even get anything coming out of the tip until you squeeze the trigger next time. If you don't do it this way, or follow their instructions, you might just have a runaway can of foam that ruins both the foam and the tool.

Super easy to use and clean.
