Do not buy from Pixco
I ordered two adaptor rings from Pixco. The items never arrived, despite the fact that I paid upfront, as is usual with online orders. They keep on sending me mails to give them feedback on their good service. I have replied to them them that I have not received their goods, but no response, just another mail asking that I rate their service on Trustpilot, hence this writeup. So beware, I would not recommend you buy from them. I do not not really what is going on, its either very bad service or a scam. But anyhow, I spent the money and got nothing in return.
