These are fairly new to us. The setup and build are a little complicated for my taste but so far they are holding up well. I am not a huge fan of the desktop being in four segments and I suspect it will not maintain rigidity over several years but for now, everything seems tight. The adjustable height feature is a new must for us but I can't say that the quality of this particular design looks built to last. I would probably give this a four and a half at this point if they had the option but because of the overall feel of the quality it gets a four.
