It does what it is supposed to do, it appears to be very strong/ So strong that when I tied it to the legs of a wicker set that I have and decided to place on my dock- ( put the cover to protect it from the birds) I could not find the set in the morning - the wind blew under it and lifted the set into the water! Luckily we were able to fish everything out. The cover was undamaged! so worth it.
