I ordered few different brands of the same locks on Amazon, oil rubbed bronze privacy door handles. This one is the best of all, not only the price beat them, but also the quality is better than the others that cost more, ordered price between $90-$1801, this company uses the box with their logo, all others just use generic brown box, no big deal, but they also listed all the features and specs of their product on the box, that shows more promising from the company.2, I ordered 10 sets, the finishing/color of Supstron's locks are more even and perfect, no scratches, no dents; the other brands, scratches, dents, happens to at least to one handle of each brand.3, structure and built, Supstron's locks are very sturdy and well made, they use solid bigger pieces inside the lock, other brands use smaller pieces to build the lock. Supstron is cheaper but the inside of the lock is better than the most expensive one($180) I ordered, the lever handles are about the same.Just advice, they have a install video, towards the end showing "before and after" they switch the handles, it is incorrect, the end of the handles should be curl down, not curl up, all other photos they posted are correct, the end of the handles are curl downward.
