I like the build quality of the 18v & 36v Makita tools
The batteries, however, leave me with a sour taste in my mouth.
I have the top-of-the-line brushless hammer drill, and I have 3 if them. I don't use the hammer drill function very often, because I also have the 36 volt rotary hammer. I also have the top-of-the-line brushless impact. I rarely use it, because of my 12 volt impact. Oscillating tool, right angle drill, drywall screw gun and cut out tool, circular saw, reciprocating saw, and I have the 10000 lumen work light. All really good tools.
I use exclusively the 5.0 batteries and I run through them like Tic Tacs it seems like. I think I have narrowed it down to my hammer drill causing a short battery life. Primarily, when I'm using large hole saws - 4 inch or more. I just recycled 8 batteries from the last 6 months and bought 6 more.
Four 12 volt stuff, I have Bosch. The little impact driver I have is about the most compact I've seen. It's a real Beast for its size, also. I can't say enough good things about that little impact driver. But that's where my infatuation with Bosch ends. I've got the small single hand reciprocating saw, two different styles of oscillating tool, a right angle drill oh, and a couple of other tools I don't even bother bringing out of my garage anymore. Completely disappointing.
I just bought a 12 volt Milwaukee impact driver and single hand reciprocating saw (hackzall) that I haven't opened yet. I'm going to have a garage sale and see if someone will take all of my boss off my hands. I'm really going to miss that impact driver though
