This desk is amazing, and the size I chose (28" wide) is especially useful for those with smaller spaces to fill - given it's width, it is probably best suited for a single larger monitor (mine is 24"), or 2 smaller monitors with center bases, situation. There were a number of size options from this brand, so measure carefully and choose wisely.Fit: I have a horseshoe shaped desk that covers a 180-degree arc, 17" deep all around, so it was a challenge to find the right size stand-up desk. I did have to give up a couple of inches of seating area, which was a small price to pay for the added comfort of being able to work standing up. I only had to shift my floor pad out a bit, and scoot my foot rest in, and I was ready to rock and roll.Setup: it was really easy to assemble this desk. One of the screws for attaching the keyboard tray was missing - when I contacted the company, they were very fast to respond (less than a day) and gave me a refund for the cost of purchasing a new one (and for the hassle, very generous). I really like that the mechanism is not powered - one less plug to worry about, and one less piece to add to the build process. The desk comes with a couple of generously sized and adjustable cord loops, so you can wire your equipment however you want. Make sure your cords are long enough to handle the desk at its peak - I purchased USB extender cords just to be sure, and I used them on all but one device. My desk is not against the wall, so I anchored the base of the cords to the leg of my desk, just to keep them from floating all over the place.Operation: the desk goes up and down incredibly smoothly. The flipper lever under the right arm of the upper tray is convenient; I find it best to stand first, then flip the paddle, but that's just because of my cord setup. The rise is fluid and not too fast (not like an office chair, where you're either propelled to the ceiling or dumped to the floor).Functional space: even with my monitor and low-sitting wide speaker bar, there's plenty of room behind my monitor where I keep a dresser tray of things like dongles. There are "wings" on the upper tray that extend toward you - they can each fit a 4" coaster (so my coffee goes up/down with me) with a little bit of wiggle room. I got neoprene coasters, just to make sure they don't slip and slide off the tray when it's in motion. Even with my water cup and coffee mug, I still have room for my phone stand, and I put my charging station behind the monitor. The bottom tray is wide enough for my 18" keyboard and a 5x7" mouse pad on either side. And in the center, the bottom tray is 12" deep, which leaves ample room in front of the keyboard for other things. I have another phone stand there, for times when I have to use it for meetings, but I do have to make sure it's secure when I raise the desk, as it can tumble into the gap if I have it leaning on the upper tray.Additional notes: I looked at a lot of different desks. I originally wanted one that compressed as mostly flat, thinking that would save on space, but it actually meant more of a depth footprint, the one measurement I couldn't sacrifice too much. The fact that the monitor tray sits higher than the keyboard tray, when the desk is all the way down, was actually a benefit: I didn't need the monitor riser anymore. If you don't have a height-adjustable monitor, make sure the 5" rise of this desk will work for you - I did have to adjust the height of my monitor to suit the change. You might want to invest in an anti-fatique standing mat - I got a small one (17x22") that has a handle, which makes it easier to store and grab, and therefore it's more likely for me to use this desk for standing work.Price: I did a lot of research prior to purchase, and this was priced very well compared to the two most popular brands, and it was the only one with the size profile I needed.Definitely an A+
