Refurbished, done properly.
Outstanding customer service. Bought two high end phones — excellent price, items were as described, immaculate. Couldn't fault the experience.

"Had my Samsung Galaxy S25 repaired today, said it would be done by 2pm and was done even earlier. The repair itself is a 10/10 — brilliant job."
"Sold my old handset to Harrison at Calatech who quoted much more than the competition. Outstanding customer service, as always."
"Ordered a PS5 Pro at a very good and competitive price of £450. Locally delivered within a few hours and in great condition."

"Came in with a faulty charging port and it was sorted within 5 minutes! Great service."
"Exceptional — sent phone at 4:45pm, money in my account 2pm next day. Gave more money than they offered online."
