I've tried rackmount tuners and a couple of other cheaper boxes, but there's no escaping this simply rules the roost.
Excellent accuracy and note acquisition, even for notes on a bass too low to be deemed safe for your trousers.Feels durable and safe to give a good whacking with your foot when using the mute function. Doesn't seem to drain battery life either. My only gripe is that for a top of the range tuner, at quite a few pennies, you're buying literally just a box. No power supply, no case. That's just the way with Boss; but it is the only thing that really holds it back.
For the tl;dr...
Pros:
Durable as mad
Plenty of functionality without being confusing
Very accurate
Very fast to acquire notes
Decent battery life
Cons
Nothing but the tuner is supplied
