These are great tools for anyone. And there are several ones to choose for particular jobs. Good value for an excellent tool! I don't think you will be unhappy with choosing one.
This is my one go-to tool. I use it everyday at work even tho' I don't do HVAC. I own two of them, one for home and one for work. I like it so much I have given them as Christmas gifts and everyone shares in my praise of this screwdriver. I use the included ream tool more than I would have tho't.
You can't go wrong buying this.
