Yes and yes. I've had one for years, I use it all the time. Go ahead and get one, once you have it you will use it all the time for a lot of different things. It's great for clearing the eye of material, take care of the thread when you do. You might burn the thread once or twice but it will not be long before you will get used to where to place the tip not to do that. I don't completely shape hair bugs but for cleaning things up you can't beat it. If you burn to much it will stink, as far as control to amount burned once you work with the tool awhile you will "gain" a good working knowledge of what to do and what not to. Your going to break a few eggs at first, don't let that stop you. I have the rechargeable batteries for mine, just have two sets, when I notice it not heating up as much I charge the other set. Oh, and yes it is very hot it will burn you. In case you do get it, turn it on and wonder about that. Ask me how I know. :-D
