    by mark from Katy, TX

    This is a first try using this hinge and also the first hinge I've used with Shaper Origin to cut the receiving part. Its tiny and I'm not commonly using tiny so can't compare. I like it and I'm interested in using this one again.

    Would have given a five star except screws that are sold along with drawer slides are shipped from a different location, presumably by a third party retailer. Tracking says shipped by USPostal Service which is slow and unreliable lately. Been 2 weeks and
