I have had my phone fixed twice with Quick Mobile Fix. The first time was great - a cracked glass screen was replaced and the phone returned within a couple of days. The second repair was first a disgnosis to confirm that a new screen and digitiser was needed, then the repair itself. Service wasn't quite so fast - about four days, which is still quite good. However, the GPS function didn't work when I got the phone back. This turned out to be the screws holding it together needed to be tightened just anothe half turn to make sure the GPS antenna is connected. Everything is good now.
Generally I am happy with their service, will use them again if I need to, and have recommended them to friends.
