I have the Satori Sorata Pro version of the same thing. The rebranded one on ebay is sold by Quattro Sports, who also happen to be the UK seller of the tmars!
I’ve put it through its paces at Cwmcarn and CYB and it’s been faultless!
No play on mine, stripped it down to have a look and seems nothing could go wrong (it uses metal guide slides rather than the tmars plastic ones which have been reported to wear out)
I had an initial problem with the return rate not reaching the top, but increasing the spring tension on the base plate solved that and returns every time!,
When it arrived, the remote cable was a little short for my setup so needed a new gear cable and outer from the garage stock but can hardly complain at that!
For a budget post with 3 height (full up, half way, full down) it’s well worth the money (£72 when I bought mine!)
Do it! You won’t regret it!
