The Good: Everything you need, short lever, very good modulation and power, if you shut your eyes you might not know the difference between SLX and XT.
The Bad: Cotter pin pad retention, lack of adjust-ability.
I once thought inexpensive hydraulic brakes were a lost cause compared with the adjust-ability, simplicity and user friendliness of Avid's fantastic BB7. The Malaysian made M596 is the first brake I can honestly say is a worthy contender as the best budget brake ever. It isn't quite as powerful as XT785, but for most riders it really is all you need.
