Had my battery replaced on my galaxy s6, they were nice, fast, and professional... but recently had my battery start to go crazy on me shutting off on me randomly. I complained to them and they informed me not to leave it charging overnight as this could damage the battery (wich i did all night even all day sometimes). They stayed professional and informed me i was covered under a 1 year warranty. These guys beat mall repair shops by far. Would recommend to everyone
