As we're 'doing up a house' we've bought a couple of hot air guns, sanders and other power tools in the last three years.
Our main heat gun and sander are made by Bosch but sometimes we both need the heat gun so we bought spares, both Power Devil. The heat gun lasted the guarantee period and a couple of weeks. The sander didn't even manage that but we couldn't find the receipt until the guarantee had run out!
The heat gun came from Argos and seemed a bargain at around £10. To be fair, the heat gun did a good job for as long as it lasted. We used it to strip layers of gloss from doors and frames and it was fine. You melt the paint and scrape it off. Not quite that simple but that's the idea. You have to be careful not to scorch the wood but once you've got the hang of it that's not such a problem. You end up with a few bit left and some ropey looking wood but once you go over with a sander it's good enough to wax, stain or varnish
Would I buy another Power Devil - er, NO!
