yep same experience for me too; the shelves ‘wood’ is a bit crap and can warp if left in dampish conditions
you can cut a better board though from something else.
As others have said, i got the metal framed ones with mdf shelves and figured I’d replace them as needed. A year old so far and no issues but they have stayed dry. Anything which may be wet I put in a small box on one shelf. I’m sure i have also exceeded the recommended weight.
I’ve bought loads of this a couple of years ago. It’s still going strong in my (second) garage that’s by no means the dryest place. Takes very little skill to assemble it and doesn’t rust, don’t miss putting the little plastic feet on the legs, and when attaching the middle braces, bend the tabs back on themselves so they can’t slip out.
