Suspicious product Neo 2 Smart

Hi,

I just received my Tacx Neo 2 Smart two days ago and have been driving it twice now. There are a couple of things that I find a bit strange:

- The box was opened before, one of the stickers was broken, the other one lifted

- All parts are inside, the polybags were sealed and opened by me

- It runs a bit strange - quite some rumble, for sure not smooth

- Outer box says T2850.61, housing says Neo 2 Smart (silver sticker) - but the rating label underneath says T2875 with production date of 2021...

What is this? I am very much tempted to send it back to the shop, because this seems just weird...

Any hints, comments? Why are the model numbers different?

Thanks,

Chris
