Although I haven't made a spin on it yet, I can tell you two things about it based on the other ones like it:
1. Be very careful with the respin cost. It can clean your balance in a few spins.
2. Each respin has a different RTP, most very low, some maybe even lower than 90%. The 96.58% stated is only true for one or two respins (from the thousands possible respin combinations). Or in other words the 96.58% is only true for the best strategy (probably the most expensive respin).
You can try it yourselves with a very cheap respin, like this one on 2nd reel for 0.02

Very few possible combinations, should reach TRTP (for that particular respin) soon enough. 2000 respins maybe, or 5000 to be sure.
Try it at VS and see what MyRTP will tell you. I can guarantee it wont be anywhere close to 96.58%, probably more close to 92%.
It makes sense if you think about it.
