It is a decent piece of equipment, and it does what it says it should do. Even more so, it certainly manages a 27 inch display with ease, provided that said display fits under the maximum supported weight limitation. In my case, it was a little over 6 KG, which is something one would like to take into consideration when buying a display if it is intended to be used together with an Ergotron monitor arm. Other than that, it could be considered a bit unwieldy because of its size, but is perfectly manageable when using two hands. For smaller displays (19-29 inch) it can be moved around with one hand as well. Been considering getting another one of those as well. I would certainly recommend it. The only minor nuisance perhaps is the cable management solution but it is also perfectly usable and once in place is hardly of any further concern.

SUmmary and verdict: Buy it if you need it! For heavier/larger displays go with the MX (trading off some flexibility). Although officially only up to 24 inch screens are supported, given that the screen weights less than 7-8 KG, 27 inch screen can be attached without a problem as well.
