Just received my TR5000 treaddesk today. Really impressed with the quality and robustness of both the treadmill and the table.
Obviously a lot of thought was put into the design of both. The desk was thoughtfully designed to assemble easily and strongly. Little things like a little lip on the arched brace to hang it in place until screws can be attached show attention to detail and give me a very good impression of the overall product.
I am about 225 lbs (with hope to drop below 200 soon) and the treadmill is smooth and never jerky even at the slowest settings.
I purchased an Ergotron monitor stand and am using an old 22" HP monitor I have which really helps to keep my head up and easily focused on the screen. The desk is nice and strong and thick so the Ergotron stand seems really stable on it. I was worried the monitor was going to shake and thus make me lose focus. But I had nothing to worry about. Monitor sits very still while I am walking at 1.6 mph.
Starting off slow today but will eventually get up more time and faster speeds. I think this product is expensive but the quality shows its expense and if I stick with it (and there is no reason I shouldn't - I gotta be at work everyday programming for 8+ hours) this is going to be a life changing product for me! Therefore, the value in this product has huge potential!
