My spiderfarmer has lasted for three years so far with no zipper issuer. i should have bought another one instead of going for the cheaper price of the AC infinity which had zipper problems since I got it. I have to be careful opening and closing it so it doesn’t get stuck. Had to cut out a piece early on. I would definitely look at the reviews. The SF is much higher quality but you can’t see it thru the pics or picking the thickness of the material.
