## Customer Reviews

### ⭐⭐⭐⭐⭐ Very satisfied!
*by B***S on March 23, 2024*

Well-constructed and sharp looking! Installed perfectly! Thank You!

### ⭐⭐⭐⭐⭐ STURDY, slightly difficult to mortise/install
*by A***R on October 1, 2022*

Worked great for my flip top/fold down desk. VERY sturdy. A bit challenging to install but that is the nature of drilling and chiseling out the wood, not necessarily the product itself. Worked on 3/4 furniture grade plywood but it's CLOSE...only 1 layer of ply on top and bottom (on the shallow facia part) but more wood in the back holding everything firmly in place.

### ⭐⭐⭐⭐⭐ Truly incredibly designed hinge.
*by V***0 on December 19, 2019*

The hinge itself is a work of art. It's a bit of a trick to get the mounting holes mortised just right, but they provide excellent directions to assist. Once mounted, the hinge is solid, and invisible.
