We bought four of these units --a previous version, the 0170-D, some years ago and they have served us well. Strong, durable and the drawer glide rollers function today as well as when we purchased them some years ago. It's amazing how much stuff fits in a drawer --no sagging, and I might add, very attractive. We are a little sad right now as two of the tops got broken in a recent move (careless movers stacking heavy items on top of them) but the units themselves held strong! The newer models come in a different color now... we looked at them at a local store and they appear to be built just as strong as the older ones we own. We highly recommend this product; it is a good investment.
