"This item appears to be a bit like marmite - and i like marmite! Granted, i treat these things as if they're disposable - buying one with every job if i can't think of where one is, so long term reliability i can't comment on, but every time i've used these they seem to work fine. With such a simple tool, it shouldn't be hard to get right.
Hopefully things like a stronger handle will be added to the next iteration of this product - these problems should be found quickly in product testing!"
"I knew I would hardly had to use it again once my kitchen project was complete unless I start redecorating other rooms. Compared prices on all different highly priced guns but at the end went for No-Nonsense. I was not disappointed at all. It was easy to use. Pull the lever back, insert the filler and release the lever. A little pressure was required when filling but I guess it is quite normal as the filler are filled with thick material. I can see no reason to complain and would recommend to any DIY'er."
