Air Cushion CUP
This product was fine but if you go to fast when you use it you tend to hit these air pockets that will make a rather loud popping sound that will catch you by surprise.
The cup is too small for my size.After just a few strokes. And this is also for your tube and flip.
THE CUP insides came out .diamond strings one after the other.
The flip which was 80dollars. The bracket,or cap came off after just a few strokes. Oil was every where.My hands became so oiled. Everything became impossible. I have the blue flip,I would like to exchange my problem for something more stable
