Review: no problema - this product is exactly as advertised. not heavy duty, but very classy, low &medium duty. installs in a heartbeat and looks (or doesn't look, since they're hidden) cool. a good value. now, i do not know if they give trouble-free service for years-- i just put them in. but i'm happy so far.
Review: Difficult to align and they have a tendency to slide out leaving a gap. Otherwise good - These were a bit tough to install, you need a 11/32 drill bit to install. The precision screws needed to "tighten" in the hole don't do all that much. I recommend using a scrap piece of wood (use a larger bit so you can get this out without damaging) to test you install before doing your final install. They are tough to line up just right.

## Questions & Answers

**Q: Which is better for drilling the hole? Forstner or twist drill?**
A: If you are drilling into the end grain, then a twist drill bit, if drilling into side grain then Forstner bit.  Also, keep in mind that with these hinges, size matters: use a 12mm bit for 12mm hinges. Don't think a fractional bit will be close enough, it isn't.

**Q: Does this  hinge have friction or torque to hold position without swinging freely? Do they make a barrel hinge with torque?**
A: It holds by friction.  Doesn't quite swing freely,  but doesn't necessarily hold it self open...hope that helps...

**Q: How much weight can these support?**
A: I don't know, look it up in the specs.

### ⭐⭐⭐ Not very stable
*by A***L on July 17, 2022*

I used these for a lid on a 15-sided, multi-tiered jewelry box. It works well enough, but I could only use one because of the shape of the box. Expected it to be more laterally stable and it actually moved all over the place. But it opens and holds the lid ... as long as you don't mind re-aligning the lid so that it's seamless.
