I've had this shelving unit for over 10 years! Unfortunately, one cracked when I set my airfryer too close to it. I immediately went online a purchased not only a replacements, but a second unit! I live in a small NY apt and so I must make good use of every open space. Over the summer I plan to purchase two more to attach to other windows to provide shelving for my plants. I love the glass design as it feels a lot cleaner than metal or wood. ALSO, mounting is BREEEEZE!!!! I've never set up a shelf this quickly and effortlessly! I would also like to note that their customer service is superb! There was a minor issue where the wrong size glass was sent to me; customer service responded in less than 24hrs and rectified the issues immediately! I highly recommend this company and their products!
