Portable Intelligent Handheld Hot Air Gun - Perfect for DIY Crafts, Electronics Repair, and Heat Shrink Tubing

I was continuously having battery contact problems with my old replaceable battery trimmer. This trimmer solved that problem. It seems to do a good job keeping my ears free of hair so I can use my earbuds. I don't use it on my nose where the hair is more course, so I can't speak to that. At first I couldn't figure out how to turn it on because there is a safety feature that prevents accidentally turning it on when storing or transporting it; you have to hold the on/off button down for a second for it to start.
