Looks like I've bought a clone too unfortunately. I didn't know clones were even a thing until it was already here. The wiki and this discussion group thing need a much better design with more obvious in-your-face presence and cohesion to help direct us users to the right info fast. Took me 5 minutes from signing into groups.io to finding the join button, and "where to buy" and info about fakes should be glaring back at me as soon as I go to the website homepage, not hidden behind a small plain text link in the top left.
Anyway, mine is having the same symptoms as Robert Entwistle. Works fine on the software that comes with it, but try to upgrade and tests 5 and 7 fail, roll back the firmware and they pass again. The packaging looks completely genuine, the circuit board is blue and the performance seems a lot better than most of these clones. TinySA seems like a great product but if you're going to have something manufactured in China and sold through Alibaba / Aliexpress, the market is bound to get flooded with clones when it gets popular. I bought it from an AliExpress store called "Convenient Tool Store". There is an absolute dead giveaway that these are fake in Robert's photos and mine is the same, but I won't say what it is for Erik's sake.
