Yes, I think it is probably a variant of the Shetland Attack Pony, with a bit of work to productionise it and make it cheaper. One of the risks of open-source software and hardware, you can't prevent anyone doing that. It has the same limitation as the original, no distance measurement, which in all fairness would not be easy.
If I were buying one, which I could not justify right now, I would get the local product. Not so far to send it for repair when the inevitable happens.
I confidently predict that the next similar product will be made in China, and will be even cheaper. Not so sure about the quality, though.
