You're on your own with these - figuring out where to place them on your doors. They break easily so I recommend ordering an extra pair (very cheap). But the lack of a precise way to locate the hinges adds complexity for the DIYer.

Using these on the canopy of a 310-gallon fish tank and they work perfectly. Soft close and lift assist work wonderfully.

Our ten year old drawer wouldn’t open or close all the way. I ordered a replacement on line and it works perfectly.

Undersink mat arrived quickly and unscathed. The package was marked "fragile".

The transaction was smooth. The product arrived on time and well packaged. The product was as described. The quality of the product seems good. I would recommend this company.
