Bests & Worsts Reviews from Amazon

I bought this back in Dec. 2016, upon arrival, I plugged it into the 4Runner and it connected and gave a clear readout on the free app, exactly as it should so I spend $10 and bought a more in-depth app to monitor the vehicle and diagnose any issues. It worked just fine for about 2 hours then, never would connect on ANY vehicle. I contacted foseal and after waiting several days, the response was that I may not be connecting it to a compatible, I assured them that this wasn't the first time I have used a scanner and that it was an OBDII vehicle, also that I tried it on several vehicles. after a few back and forth emails, they promised a refund and a replacement but, the replacement wouldn't be sent until I removed my truthful yet bad review (an obvious bribe). I removed my review and had no contact from them after several attempts to have them make good on their promise of a replacement. I pretty much forgot about it until about three weeks ago when I got an automated email, asking for a review of the product I had received. I sent an email to their customer service with the automated email attached stating that I was never furnished a replacement as promised and that they shouldn't ask for a review from a customer that received a POS useless chunk of crap that failed after 2 hours of use. I also asked when I would receive my replacement that had been promised, I was told that I would receive it "soon". I told them if I didn't receive the replacement within a week, I would reinstate my review since they were kind enough to remind me.So here we are three weeks later, with no replacement and no email from them explaining when or if I would receive it. DO NO BUY FROM THIS COMPANY, THEY ARE FRAUDS! The item cost me an additional $10 that I now cannot get back due to their junk product, I also paid for return shipping $5 with the promise of a replacement. Item worked flawlessly for a very short amount of time, just long enough to give me the confidence to spend additional money for an app that I have since used with a different product that works as it should.
