Review on Knobonly 21" Soft Close Full Extension Drawer Slides - 10 Pairs With Locking Device Included And 85 Lb Load Capacity by Brian Quenzer

Customer wanted new drawer boxes with undermount slides and didn't want to spend the money on Blum's, so thought I'd give these a try. First, they arrived pretty beat up and one set of the slides has a bent upright which I'll have to try to bend back to use, but luckily I only needed the other 4 (bought a 5-pack) for the job.The instructions are horrible and in metric. Luckily I found a good YouTube from Bourbon Moth Woodworking that went over the installation. Once you know the tricks, they are very easy to install. In the end they worked great and close very nice.
