Just completed replacing 6 drawers with Blum Tandem Plus slides with these Tandem Plus BluMotion. The replacement process worked very easy and had each drawer completed in about two minutes. The glide action is very smooth, height adjustment easy to set and the soft close works perfect. The customer service at Woodworkerexpress was great and they were very helpful verifying my order and making sure I had all the necessary parts like drawer locks (which I didn't need to replace). A firm five stars for both the product and service, way to go Woodworkerexpress!
