Fast delivery. Phone exactly as described. I ordered an extra lead and the wrong one came. Contacted them with a reply straight away and a new lead was sent express post. Could not get any better service
The phone arrived in great condition! Delivery was slightly slower than expected but I'm sure that had to do with the postal service rather than them. If anything I made a mistake regarding delivery details with my order and the customer service team got back to me promptly and assisted me immediately which allowed me to receive the product quickly regardless. 10/10 Service and product!
