Have purchased items from them for years. Recently purchased an OLED display for $39. After the display arrived I wired it up exactly as directed on their web site. The display did display an image but the image was VERY VERY dim. I tried a different library but still way to dim to work with. I contacted "customer support" and informed them of the problem. They directed me toward their forum for assistance. After several days of no response I emailed customer support to inform them of the no response. A support person did post on the site requesting additional information. I provided that the same day. After several more days I did not receive a response on the forum. I again email them informing them that I was not satisfied with the support I'm receiving. I was then banned from their site and could not even track orders I had still in progress. They did refund my purchase of the OLED but then emailed me asking me to seek another vendor. A very good suggestion.No phone support, no direct email support, never contacted by the same person and a very bad attitude when things go wrong with their defective products. The OLED display was not produced by them but they sell it and wont support it. They act like a bunch of children.
