I needed to repair a broken battery cover on my wife's mobility scooter. I'd seen heat staples used before and finally pulled the trigger and bought one.I looked at several of the less expensive ones that only hold the staples in one position before deciding on this one that has 3 positions, plus 3 heat settings.You also get 100 ea of various types of staples--inside corner, outside corner, straight, wavy--wavy in two thicknesses as well.NOTE: You can buy this same exact machine for about $20 more, but the only difference I see is that the more expensive model has a carrying case.Just do what I did--get one of the tool bags from HF, and some old pill bottles for the staples, and put the whole thing in the bag.The biggest thing I don't like about this is that the cord to the handpiece is thick--probably because of the current it carries, but it makes it a little awkward at times to use it and maneuver it where you need it... not a deal breaker, and ASSUMING this continues to work properly I'd highly recommend it.
