TOPDON TopScan Lite OBD2 Scanner Bluetooth

I don't remember who recommended me to purchase this thing. But it's such a crap omg. Not only you don't get that first free one year subscription (I've payed additional $50 for that subscription). But it also works very, like very bad. In short: 1) The app requires internet connection. You cannot use it without signing in, and it's an issue cuz it will drop your login session once in a while. And I don't have a stable WiFi connection in my garage, and it's such a PITA to use this app. 2) There's not all car brands. It works for Subaru, and for Mitsubishi. But there's no Lada (which is basically rebranded Renault). Like any no name $10 OBD from AliExpress will have that car brand supported. But not TopDon TopScan for $80 + $50 subscription. Oh my gosh. Double check if you're car brand is supported. 3) I've tested it with Subaru WRX STI 16", because I did a coolant flush and all I needed is to watch coolant temperature graph (when burping, in order to see when thermostat was opened/closed). But no matter what I do, there's no such data in TopDon. Be sure I've spent hours trying to find that information. Such a simple task cannot be done with TopScan. 4) Issues with connection. For some unknown reason, TopDon TopScan DOES NOT connects to your car. And sometimes it can't auto read VIN number. When it happens, you must enter your VIN manually. The connection is also very unstable, even if you're like in 1 meter away. 5) Eventually, it did not helped me. Thanks god I had a no name OBD from aliexpress, that I've purchased years ago for $10 or so. I've connected that thing instead of TopScan, and it successfully connected in a matter of seconds. That old no name OBD automatically read my VIN, detected the car brand, and just worked. I've had to click literally 2 buttons to access Coolant Temperature graph (updated in real time). By the end of the day, I was so disappointed. Maybe it's a good product for things like ABS brake bleeding etc. idk. Just sharing my experience, so you understand what you should expect in reality. Total waste of money and time.
