My Uncaged Ergonomics RISE UP electric sit/stand desk frame arrived and, I have to say, I was a bit nervous about it. I went with this option over the much more expensive iMovr Lander option ($750+ desk frame) and other more expensive options like Jarvis (which I already own for my wife's desk), UpliftDesk or Standdesk ( all 3 around $450-$550) so I was expecting a tough build and a product with some flaws.My first observation was the packing, It was incredibly well packed so there was no chance of damage during shipping. I mean, really, really well packaged. Once I opened it and reviewed the instructions, I got to work on the build. It was simply designed and well engineered. No problem with missing parts, poor paint/welds, or mis-aligned screw threads, etc. Really no issue at all putting this together. All in, it took right at one hour from start to finish and I was going slow and easy. The instructions come as a single page that has illustrations that are easy to follow and well worded. No problem expanding the desk for my 6 foot long desk and it could easily go wider out but I didn't measure how far to confirm the max distance. They provide all the hardware to mount your desk to the frame, secure the electrical control and include stick-on "zip like" ties for cable management. I was also surprised to receive 6 rubber spacers for use between the frame and desk top. I'd read DIY guides recommending you add these...and Uncaged Ergonomics had already included them.Once built, I checked the heights to ensure they were true to the specs. It has a low height of 26" and max height of 52". It easily lifts my 6' by 3', 100 pound butcher block desk top with my PC and Monitor on the desk. No problems at all. It is also quiet and lifts fast but starts out and stops smoothly so no jarring at all.I am really impressed with the quality and the price is unbeatable. Do yourself (and your wallet) a favor if you are going the DIY route and get this frame over the other available options. My initial impression is this desk is sturdier and better built than the Jarvis desk frame. Time will tell if it also has a solid reliability record but it is off to a great start.
