Well I don't usually have bad experiences with a vendor but I have run across a vendor that appears to be a bunch of crooks.
Back in August I order 26 BSNPLN-10TH16 sleeve bearings. I finally got the order in November with 10 of them the wrong size. I got a RMA and return them for replacement. Well they received them and never sent the replacements. In December a month later I contacted them and they were refund the amount for the returned items and for me to re-order. Having a bad feeling I waited for the refund. It has never showed up nor a credit on my account with them.
So please be aware that Designatronics, Inc out of Hicksville, NY is a company you do not want to deal with as they are dishonest. They basically took my money and never full filled their obligation to me. I will never order from them again and recommend none of you order from them either.
BTW their website is https://shop.sdp-si.com and support email is qbcsupport@qbcbearings.com
