Alright, we just bought a couple of the "Easystow Fenders". They were expensive for sure.
but....they are much better built than they look on the website. We bought the heavy duty 12" x 60" size and the skin is as strong as the taylor fenders we have.
There is an inner skin that is the actual thing that blows up and then the outer skin. Although we don't use the recommended pump to blow them up (we use a regular bicycle pump with an adapter) it goes pretty quickly and once blown up they are about as solid as the taylor fenders. I suppose we could pump them up to be rock hard but there has not been a reason to.
You could easy fender
board them if you were concerned about nails and such but I expect that they will last as long as the Taylors. If a nail is going to go through one of these its also going to go through a Taylor. There is no valve to go bad, just a rubber tube that folds onto itself when you want to close it. It tucks into a space that keeps the UV off.
The loops used to attach them are very thick and sturdy (nylon I assume) and sewed with thick thread. There are three loops on each end. If here were one criticism I would say they need to add mid loops along the length.
We had them between our boat and an end t-dock (that got a lot of wake action) for a month and they held up very well. They seem to adjust well to the tide and being long they didn't need to be adjusted along the boat, even when the wind
changed directions against the spring lines.
They roll up tight and to about the size of mid-size Taylor fender.
In a year or two I'll come back with a review of them to see how well they hold up.
