Unfortunately I only used it after the return period. I had to so I could return it. It overheats and shuts off after 30 seconds at best. I'm not sure what kind of project you can do in 30 seconds, but this is a very inconvenient and messy job where you unexpectedly have to leave it for 5 minutes over and over again. There is only ON and OFF, no temperature selection. You'd think it's built to withstand its single thermal setting, but it's not. Garbage.
