"I buy these for our maintenance team as, having tried many other both cheaper and more expensive sealant guns, this one has been the most reliable I've come across. Price-wise certainly, I don't think you'll find a better alternative."
"These guns far outlast the cheaper versions. Its worth spending a little extra for quality as if it fails in the middle of a job you will wish you had bought one of better quality units. I don't recall one of these ever failing but often end up giving them to some one to help em out of a tight spot and then collect a new one."
"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."
