Looks good, but doesn't deliver what it promises.
This review also applies to sizes F2, F3.
Ordering and delivery were, as is typical for SVB, first class. Thumbs up.
The fit of the F socks is good, assembly is easy. They look good. Up until then, everything is great.
Now, after just over 4 months of use on the boat, and several locks, the defects and weaknesses are becoming apparent. One sock has already worn through due to rubbing on the jetty, and two more are about to.
In locks on dirty walls, the socks prove to be real dirt collectors. If you don't make sure to clean them as soon as possible, you'll have a real sanding block hanging on the side of the boat. Cleaning them isn't that easy, however, due to their structure.
If you just want to spruce up old fenders, you can use them. For real fender use, i.e. cushioning and protecting the boat, protecting the side of the boat and not rubbing it away, they are of only very limited use. Simple new fenders are definitely the better choice. Therefore only 1 star.
A warranty claim for the worn-out sock was refused.
