The guides are very similar to slides from other manufacturers, but not as good. I bought 6 pairs, but all four slides in two packs that I opened had the same problem - rubbing/crunching an inch or two before fully closing. I just completed 6 identical drawers from a large store and none of them had this problem. I can't understand why this product has such good reviews for such performance! I could still send them back and see if I got a bad batch or something. I bought two more sets from a large store today to compare performance after installing a drawer and they still compare poorly. I will report to see what the supplier is/is not doing.
