I researched hydraulic desks. One stood out fro the rest, but had never heard of the company. Bought the desk anyway, working from home, figuring I could return it if I wasn't satisfied. What a hidden gem. The desk is easy to assemble. Has programmable heights or raise and lower to your satisfaction. Quiet operation. AND NO SHIPPING COSTS. I paid $239 for the desk. It's now been reduced to $229. It is below the cost of comparable desks and all the other companies charge a shipping fee. I like it so well, I'm going to buy a 2nd one for my personal computer. I'm frugal with my money and was happy with the cost, free shipping and ease of assembly. The model I got, (from Amazon) is PTESD-S3B
