"I have one of these from around 14 years ago. Fantastic quality and to be honest I thought they had stopped making these for the nasty little plastic ones that seem to be around. I still use my old one, but I promised should I ever see any when I was out I would get another - just in case. I haven't seen one for years and I have purchased 3 or 4 of the plastic ones (to get me out of a bind when out on a job) but that's about all they last... the one job. My only worry is my current model will last another 10 years and I never get to unwrap this. Highly recommend this - grab one before they go again."
"A lot stronger than the plastic ones and should last a long time. Useful pressure release leaver to stop oozing. Takes all sizes of cartridges. Ticked five stars for reliability but cant really comment on same as only just purchased but from build quality should be OK."
"My previous gun required me to release the pressure on the cartridge each time I let go otherwise the silicone would seep out and make a mess. I don't have the problem with this gun. Performance is good but can't give it three stars for reliability as I only used it a few times. It's well built for the DIY'er like me but can't comment whether it will take the punishment for trade or site work. Very happy with the purchase and would recommend."
