Received my switches that were over lubed and either typed 3 letters every time I pressed down on one or didn't type at all. There was something wrong. I'm using the same keyboard right now that I used with those switches and it works great, as it always has. Sent them back with USPS, and shipping them back costed me $30! All in all, I got my money back but they didn't give me my money back for shipping. If their Chinese workers they are paying 4 cents an hour to knew how to lube switches, this would have been avoided.
