- 5 of 5 Perfect February 18th, 2009
by chris from Ajax, OntarioGreat product, with a jig it's installation is a snap and has a unique look, the product was used throught out the custom built home.
This review is about a different size/color of this item. (UIP-218FRUS26D)
- 5 of 5 SOSS 101 Invisible Hinges April 8th, 2026
by Richard from Mukilteo, WAThere is a marked difference between the SOSS 101 invisible hinges and those made in other countries. The quality, fit, finish and the smoothness of operation of the SOSS hinges is just superior. Yes, they cost more but is your project worth the cost in long term.

- 5 of 5 Pretty ingenious March 3rd, 2026
by Travis from Golden, COThese things are super cool and seem like they solve some problems in a unique way. But beware: they're pretty fragile! Don't expect to be able to test fit them and remove them over and over, or you'll break them (speaking from experience)

- 4 of 5 | June 7th, 2026
The drawer pulls are good quality and have a nice finish, but the quality of the long fasteners is very poor. The hardware is made so can be cut easily but the threads are very poor and cross thread easily. I will have to buy better fasteners, I don’t see
