    Great shelves

    Better than expected! Wanted shelving in the kitchen after our remodel but custom cut would’ve cost us over $500. Glad we went with these. Quality is great, easy to mount. I won’t be coming close to the weight limit but even with pressure they don’t budge. Anchored into drywall and 1 stud. Great price and perfect for our space.
