We buy on average about three of these type of guns a year, we have bought cheap Chinese ones for about £5, expensive so called professional ones for over £20 and now this circa £10 Bondit one. They all basically work the same but the £5 unbranded ones are more difficult to accurately control the foam flow and on a daily start up need a hard pull of the trigger to get going resulting is a burst of foam being ejected. The £20+ ones look posher with die cast aluminium bodies but don't actually work any better than this Bondit one. The Teflon coat on this Bondit gun seems to be more decorative than functional as the dried foam still sticks to it like glue, having said that scraping it off does seem to be slightly easier than on the uncoated guns but as I have said it still needs to be scraped off with a knife. The reason we get through so many guns is that we use them for a few months and then not all for several months, during this non use period the foam hardens in the non-return valve under where you screw the foam can in and removing it is a very time consuming job and often results in the valve leaking so can changing becomes a very messy job. We have tried both running gun cleaner through immediately after its last use as well as just leaving he can on and both have the same result, new gun required. Having said that this is our first Bondit gun so who knows it may actually work in a few months time when we next try and use it... We only use fire retardant foam and this is the foam that causes the gun failure problem. The adhesive foam we also occasionally use does not seem to cause this problem so the gun we use for that keeps on working. One last tip, when you first attach a can of foam, never just give the gun trigger a quick pull unless you hold it on to get a good blob of foam discharge. Failing to do this will result in the foam reacting with the air already in the gun and within an hour all the foam in the gun will have set and you will then have hours of cleaning to do or, buy another gun...Read full review

Teflon has a great resistance to solvents like acetone. Gun cleaner is made from acetone but if you soak it in acetone the 'teflon' paint peels off so I didn't think much of that. The nut wasn't tightened properly so it leaked foam into the trigger action. Even though I cleaned it thoroughly inside and out the little ball seal got jammed up. To cap it all, two out of the three Instastik canisters I used leaked all their propellant after I'd removed them to clean the gun. I went back to a conventional cartridge glue after all that mess. No more foam glue for me.

I'd never used one of these before so I was a bit apprehensive as I was aware that expanding foam can set quickly. It's easy to use and easy to clean with the correct gun grade cleaner. I also discovered that you can disconnect a can of part used foam clean the nozzle of the foam can whilst spraying cleaner through the gun. You can then reconnect the can of foam when you're ready to use it again. The foam and cleaner comes out with some force so beware of where you're pointing it!!

I’ve used this item every day for month highly recommend this product and the useful tubes to help application of the foam. Holds a Hilti foam can perfect unlike others out there

This is a very useful tool, far better than hand held foam. You need a lot of foam gun cleaner, and more importantly you will need to dismantle it to clean it. That was quite difficult, and a manufacturers diagram would have been helpful. There is a tiny spring on the non-return valve, that seats the ball bearing. I've lost mine.
