These fenders are difficult to inflate and even worse to deflate. Further, trying to report or contact people is a BIG problem with Vevor. Unless you "attach" an .MP4 file or some other obtuse file format I don't recognize you can't submit your question. I've reported this in the past and they promised to address it. They have not. It appears that Vevor is on purpose limiting contact with them.
I've bought a fair amount of stuff here.....I've about reached the end of my rope with this.
