Just a thought to add. I'm a Bosch 18V guy. I like it. Bosch has had somewhat limited offerings. So I have some M12 and M18 stuff. I really don't want 3 platforms. So when I needed a M18 battery, I bought an adapter for a Bosch battery. Works great. When all the M18s die, I'll buy adapters and will be on 2 battery platforms. I see no reason not to own multiple brands and battery adapters if they are available and I prefer 1 brand for a certain tool over another.
