Works very well for easy to install and adjustable shelving. I'm not sure how much I would trust a deep shelf or lots of weight, but It works great for a 6" deep shelf with light to moderate weight. If you need another inch of height, just pull the board/shelf out and move it up or down a slot or two. Great for odds and ends storage in the shed or garageLove this product. I am able to use unused space in my garage to hold paint cans, cleaning agents and the like. Had to buy more nails as there were not enough to use every hole to hang product so it more sturdy.I guess I could have skipped to every other hole in which case there were enough screwseasy to install to allow for shelves between studs in my shed. cutting pieces of wood for the shelves however was challenging (must be thick enough, right width, not too deep, etc).but a big help to keep bottles and other things tidy and off the floor.the price is somewhat high in my opinion but i applaud the creative but simple design.Strong, sooo easy to install, work great!!!I think it is overpriced for what it is, but it is a solid product and great to use in limited spaces.Easy to install, a little pricey for what it is, just plastic but really is a space saving option for sheds or garages with open studs.Pretty easy to install. Twisted stud was a little tricky, but still worked great.Time saver and a great tool for maximizing space in your shed!
