We loved the price when we bought them in July and they fit quite well it wasn't too difficult. As with any drawer slide, you usually don't want to use the screws that come with them as they're usually junk, but we thought nothing of it when we got them. We only used the trust head screws and they fit really well. We were very happy with them for the first few months and then slowly but surely they started to deteriorate. It's been a little over five months since we completed the repair and now five sets out of 10 are completely out of order and the closer mechanism has stopped working. Unfortunately I wouldn't recommend these drawer slides to anyone and I wish Sprung had a little more money for more established brands.
