This thing is now my absolute favorite device around! I use it always it is just too convenient and it works flawlessly just don't turn it up over 13 watts I had one that I tried to run at 15watts and it blew the disc apart but it works great on 13 with 4 second pulls you can repeat after a few seconds and it heats quicker just don't hold down for long extended periods as it may overheat and break. You can load it way up and just keep hitting it so nice!
