Been using the battery for 3 days now.
The Good - I am a heavy user and can now use the phone all day and could possibly go two days but I charge at night, battery door fits on my 800w, the bump actually works for the phone, good when holding the phone and better for speaker when laying flat.
The Bad - not so much, phone is obviously heavier, don't like that and price is not cheap.

I really didn't think I would like this battery but I recommend it if you want more battery life
