There's only 4 cordless brands I would buy: Makita, Hikoki (used to be Hitachi), DeWalt or Milwaukee. They have extensive ranges that use the same batteries.

Black and Decker, Bosch etc are all fairly naff in comparison as their bearings, motors and gearboxes are known to wear out faster, but are still a step ahead of other brands.

Tbh no cordless tool is a 'Buy it for Life' but if you're willing to pay just a bit more you can have the best on the market that survive thousands of hours of use.
