OBDKCAN Bluetooth OBD2 Scan Tool for iPhone, iPad & Android - Faslink M2 Sensor Professional Code Reader, Car Vehicle Diagnostic Tool

There are dozens of system tests this toy says it does. None have ever worked. Retired out on multiple vehicles. It will scan your vin and thus give you make and model. And tell you if there are codes. Most codes cannot be read!

Update (11/28/2018): If they get this functioning as described, I will update this review again. In the mean time, the seller contacted me immediately, and we've been communicating through Facebook Messenger. She, Joom Doe, immediately offered to refund my purchase price, send me a replacement item, thinking this was a hardware issue, and offered to send their most basic corded scan tool at no charge, all for the inconvenience, and hoping that I will change the review. I explained that she was welcome to do all, that I thought the incorrect DTC reporting seemed more of a software issue, and that I leave only accurate reviews, to help other shoppers, but would be more than happy to edit my review, if they were successful in correcting their issues, making their product function properly. Since she was refunding, I would continue to aid her in testing until they get it right. She continued to badger me on Messenger, to go ahead and change my review, with back to back messages, as many as 7 in a row, whenever I failed to reply immediately. She told me yesterday that they had already sent the replacement Faslink M2, but today only confirmed that they will be sending the cheaper tool soon, and has not responded to any mention of the refund she originally offered. Typing in what I assume to be broken English, she said "There is no gap in the air. If there is a problem, I hope you can send a photo to prove that our product is wrong." No biggie, Amazon has a process.Original Review (11/26/2018): Worse than something that doesn't work, is something that works incorrectly, and could cost you a lot of money chasing the wrong issue. I'll try to post a YouTube video of unboxing and this thing displaying completely incorrect codes. As verified using a Snap On Zeus, the car I tested this little waste on, has a catalyst efficiency code. The faslink m2 displays it as a P0104 mass air issue. I have NEVER had a code reader that displays the wrong code. You can buy a cheaper elm327 that does everything this does, ACCURATELY. It also doe NOT program keys. It only gives instructions to program fobs, and not all of those are correct. I also could not get any info out of the enhanced module scans.
