I had good experiences with PLX prior, but recently I had an issue with my kiwi3 and I cannot get anyone to speak to me or help me with fixing it. I've tried their support email system, phone calls, and Facebook messages with no response. I'm highly disappointed because I like their products. Ive resisted posting a negative review for two months hoping I could get this resolved, but this is my last resort for communicating with them. Hopefully they see this and realize they have a huge problem with customer service
