Friendly, same-day service. The online booking system is easy and the OnePlus 3T repair is excellent. Dropped it off for a replacement screen at lunchtime and picked it up after work. Thank you!

It's now a day after I got my Nexus 6P battery replaced with GSM and I can say i'm very happy with how it worked My phone lasts about 4 times longer than it did before, and they did it for 30! On top of that they fixed another issue with the charging port for free. Their offices might not be swanky, but these guys are very good at what they do. Thanks GSM!

Wow! Talk about magicians! This place fixed my phone even after it had been crushed by a truck! It's like new! But why they are operating out of a tiny room in an industrial estate by the N Circular? The Queen should give them an office in Buckingham Palace. For free as a gift from the nation. Or maybe at the top of the Shard. Somewhere cool anyway.
