The product in itself is good but it lacks simple things to make it perfect. Firstly there is a flexible circle and you have to put the covers on the impossible circle to create effects therefore obliged to buy 2 lot. As a result it lacks a storage instructions and maintenance. and finally the zipper is bad they constantly block. But in general it does the job for which it is intended to condition not to manipulate (open and close the zipper.) The materials of covers is rather well made. So I recommend it for occasional use. I do not regret my purchase.
