Jet board recommendations

Hello all,

I have been researching purchasing a gasoline powered jet board, but have seen a lot of people claiming some brands are scams/faulty. I was wondering if anyone had any recommendations for a starter jet board. So far I have been looking at the KOOTU P1, Rush Wave Raptor EFI 02 and Blue Penguin petrol engine jet board.

If anyone has some experiences with these brands or any other recommendations that would be awesome! I have chosen these brands because they are less that $6000, not looking to spend more than that.
