I've used them in my trailers and my shed and they have worked out fine.
There not cheap to buy, but if there installed correctly they hold up great.
If you do not install enough screws, or the wrong screws there going to twist.
I do find that just using a HD rubber maid 33 gal. trash can to hold all my items like shovels, hoes rakes, axes, tamper rakes, ect. took up less space and has worked out fine.
