### ⭐⭐⭐⭐ Buen producto!
*by I***A on 2 May 2025*

Un poco alto el costo y estaría excelente un video de cómo instalar y cómo queda ya instalada la bisagra y debería traer tornillos de repuesto, ya que es confuso el instructivo de instalación. Al final se logró pero si fue muy tardado instalar y ajustar.

### ⭐⭐⭐⭐⭐ Hidden hinges
*by M***C on 14 August 2023*

Works fine. Need a good router to make the cut.

### ⭐⭐⭐⭐ Good but needs better instructions!
*by A***O on 18 October 2022*

These seem to be well made and so far work well. The actual installation is straight forward but the following changes would make everything almost perfect: 1. There should be a template sent with the unit to make mortising the holes easier. Not an actual template for the router to follow but even just a cardboard template. They do not come apart so using the hinges themselves as templates is near impossible as they wont lay flat on a surface. 2. The instructions are only in chinese. Since these are being sold on a u.s based platform i expected instructions in english or at very least diagrams that outline things with arrows to show movement directions etc of adjustments. Everyone that buys these will not know how to adjust and will probably use trial and error to figure it out which takes time and adds frustration. Overall a good product but please send out clearer instructions.
