Not impressed. Very hard to install. No hole pre-drilled or marked. Raw wood, no finish on any surfaces at all, no shim blocks, slides are difficult to pull out and stiff.  They were a struggle to install and they should have finish supplied.   After I installed the 4 I purchased, I bought a competitors product for a larger drawer. The competitors product was totally superior and a comparative breeze to install. Wood nicely finished, holes predrilled, mouting blocks included, slides pull out easily. No more of this brand for me!
