I have a Bosch 12 volt drill and impact driver and I like them. Have been using them for years. Small, handy, and powerful. Very useful in the shop. I know there are bigger and more powerful ones, but these have been good for me.
They are on sale at Lowe's for $129 for both, two batteries and a charger. I'm sure I paid more than that for mine. In fact, mine were stolen and I paid more than that for the second set. If you are in the market, check them out.
No affiliation, no kick back, nothing, I just like them.
