I would rate IWOOT 0 out of 5. The product did arrive, but with no invoice. Despite asking 10 times online since 27th Nov, still no sign of it. They started off by saying it had been sent, then that they had invoicing issues, and now I just get a non descriptive reply for their now obvious multiple choice of inane customer responses. (Including that my issue has been escalated)I suspect that I will never get one out of them, so if the product goes wrong (its electrical) I have no proof of purchase or guarantee. I will never use this company again, but I really don't think they could care less!
