7 or 8 people got one of these things at my office. and it was a pretty random assignment (for the record, i wasnt one of them and probably wouldnt have taken it had i been offered). basically there were a few free ones that were offered to 8 people (that didnt either ask or not ask for them). but all accepted. after 1 year, none of the original people that got them still have them. it took a week for some, a few months for others to give it up but in the end, everyone did. for some, it was more a function of the "ricketyness" of the ergotron device. since the whole set up (keyboard, mouse included) has to be able to move up and down its not very fixed to anything. so it wiggles and shakes as you type or click. and its bulky, takes up space on your desk, forces you to put the monitor at the very edge of the desk, killing any room on your desk for anything else you dont want to reach around a monitor and giant bar to get to. for all who used it, any benefit of being able to stand up didnt outweigh these costs. before i saw this ridiculous "study" i disliked the product. now seeing the "study", i dislike the company. unfortunate.
I'm the software development director here at Ergotron. We appreciate your feedback and I will forward this to product development. It will help us improve our product. About the study, we supplied the product used in the study, but it was conducted by Health Partners Journey Well and we have no input on the results. BTW, the detailed results and methodology haven't been released by Health Parters Journey Well yet. I am told they will release those details but we don't know when.
