I had a pair of BABZ (same as the LTU) that both developed holes within the year.
They are really just children's bouncy toys not boat bumpers.

I have since switched to these and they are much much more durable. Assuming you keep them inflated all the time I prefer them to the bouncy balls. They are much firmer so inflating and deflating is a chore if you don't keep them inflated. Mine stay blown up in my rear locker at all times and I have zero fear of them ever getting punctured or a big wave flexing them enough for the boat to hit the dock.
Just my experience.
