What Customers Are Saying

The spray foam gun is praised for its ease of use, precision, and time-saving benefits compared to traditional spray foam cans. Customers highlight the ability to better control and apply the foam, resulting in cleaner and more efficient work. The reusability of the gun and storage of the foam cans for up to 30 days are seen as major advantages. However, some customers have experienced issues with clogging, leaking, and difficulty cleaning the gun. Overall, the consensus is that this is a useful tool that makes applying spray foam insulation much easier, though proper care and maintenance are required.

Reusable value, don't forget cleaner.

Would Recommend

Better value than using the single cans. Don't forget the cleaner or you'll be buying another gun.

WORKS WELL BUT REQUIRES A LOT OF MAINTENANCE

Would Recommend

It works well but it’s too much maintenance for me. The foam container must be attached to the dispenser gun or any foam will dry inside the gun and prevent the gun from working. This can be an issue because the foam has an expiration date. Also, it takes up extra space with the can connected.

Good product, but cheaper to use one-time-cans.

Would Recommend

Well made. The only negatives are cost and maintenance. $64.97 is a lot for an injector handle, albeit, it's very well made. You will need to buy cans of injector cleaner cans. If not, then you will have lots of fun cleaning by hand.

First can, leaked everywhere, then clogged

Would Not Recommend

I bought this to use the larger GREAT STUFF red can stuff, and it leaked IMMENSELY at the entry point, oozes forever when done, luckily I put the gun down on concrete so clean up later wasn't too bad. THEN it was clogged to crap. NOTHING ABOUT THIS WAS PROFESSIONAL. It's metal, cool... I guess... Got so frustrated with it, just broke it, since the handle is cheap plastic.

Its okay

Would Not Recommend

I think this has some merit since it uses bigger cans and you can run it longer but I'm disappointed on a few fronts. First, it clogs up quickly even if you use cleaner, the first time will be the best then it will deteriorate quickly after that. The second is that they claim you can use a can halfway then stop and restart a few days later without wasting the can, this has never worked for me and I've had a few attempts. Now i just run the can out. This last use the gun doesn't even work anymore...

I didn't actually buy two of these but because Lowe's only has self checkout I double charged myself and didn't notice and have no way to fix it.

instructions stated that as long as flow adjuster is fully closed and stored upright it could be used within 30 days. I found it to be clogged and useless after 1 day.
