OMG. The website www.davismicro.com is awful place. I bought from them, but the seller asked to pay for the fast delivery and it cost me about $30. Also the order arrived after 30 days, what wasn’t fast delivery. It was all damaged and the item of course was defective too. All my attempts to change the order failed, because the seller refused to change it and told me that it was only my fault. Please, any ideas what to do next.
