Their real name is Bo Yuan e-commerce; they are a Chinese company selling in the UK as "PCAdapters Depot". They send their products from China. They sent me a charger which didn't work. I emailed them 6 times asking about their return and refund procedure, and for a return address. They refused to give me a return address and instead kept saying that my computer must be faulty or I must have bought the wrong adapter. They insisted I send them photos, measurements, etc, which I did, although they were irrelevant, as the item they sent simply didn't work. After a couple of weeks of fruitless emails and their refusal to accept the item back, or to give me any address, I finally resorted to Paypal. Luckily I'd paid by Paypal, who looked into it, found me the address in China to return the item to, and refunded me the costs of the postage and also the faulty item. I should not have had to resort to this though, the process took weeks and was very time-consuming and stressful. I would definitely avoid this company!
