Purchased RC Car. Motor failed on day 1 of being used. Nitrotek told me (quote) "We sell hobby grade products and part of the hobby is model maintenance and replacing worn, broken or upgrade-able parts." I insisted they repair or refund. They send a replacement motor, which did not work as needed to be wired differently. Also their instructions for replacing the motor were incorrect. Returned item for refund. From then on they took on a really caustic tone and became utterly acerbic and rude. This went on over a considerable amount of time, and in my view they were clearly breaching the UK Consumer Rights Act. They were saying I could not have a full refund because the car had been used and was no longer in a as-new condition. It had been used for 30 minutes before the motor blew. In the end accepted a slightly reduced refund just to close the matter and stop contact with them - which I believe was their tactic from the start. This has been the worst customer service in terms of rudeness etc I have experienced, and I would strongly recommend going elsewhere.
