Love it! The only downside
Love it! The only downside is the brackets to the keyboard panel/platform could be stronger to prevent flexing and bending from resting my hands on the front edge. Another nicety would be 2 (or more) present buttons to raise/lower the platform without holding the up/down button the whole time. Otherwise, again, a very well-built, nice product!

Perfect
Exactly what I needed for the space that I have, so far has held up my heavy monitors with no problems and is a game changer. Very happy with my purchase and have absolutely no regrets!

Great way to avoid sitting too long!
So much better than the manual sit/stand desk set up I had previously, especially with a Black Friday 50% off sale! It really helps with my tailbone pain. It&s super quick to set up, maybe took 5 minutes with a neighbor helping me lift it up.

Broken motor
Feels super high quality but motor doesn’t work. Seems like a one-off experience hopefully.

Excellent, good price point.
Durable, stable, quiet device. My monitor does not rock when rising/lowering. Good value for the price.

Average
I do not understand how there are so many five star reviews. The keyboard tray slants slightly, and the wrong direction. It also moves noticable when you rest your hand on it. Not terribly difficult to assemble if you ignore the poorly written instructions. It was packaged extremely well, and will likely get the job done.

unsatisfied with EM7
This desktop seems anything but stabile for a workstation. I have a through grommet mount for my monitors and when the desk is lowered everything is perfect. When I raise the desk the whole thing is slightly wobbly and the desk actually leans to one side so my right monitor becomes crooked. It seems like the bottom of the X frame doesn&t lock into place. My non motorized version of this desk was significantly more stabile but the keyboard tray was misplaced in the office and Flexispot doesn&t offer a replacement.

Just perfect
I really like my Flexispot Motorized AlcoveRiser EM7, it is exactly what I was looking for. The assembly is extremely easy, and it makes working from sitting to standing seamless. It is the perfect desk converter.

I can see the possibilities.
Product seems sturdy. Initial evaluation good. Assembly needed assistance due to weight but done quickly. I needed the electrical remote for my personal use requirements. I like option to move this item to different work stations.

Perfect!
I spent a whole year carefully researching standing desk converters. Hoping to save others some time. tl;dr: Just get this one. Here&s my 4-week review. Background: I have a relatively small space, with a heavy immovable desk pushed up against a wall. EVERY other desk converter option on the market had one or usually several problems, that this purchase fixed: 1. You can make it "dual-ergonomic" (able to change the vertical distance between the monitor & keyboard every time you stand up or sit down) by just buying a monitor arm (or a dual-monitor arm) and moving your monitor(s) to the arm. 2. Back of converter is not too-deep and smushed up against the wall as with others on the market. So this converter provides enough room for a monitor-arm clamp (it has a grommet-and-hole option too), and for monitor arm-movement behind the converter. 3. It lifts straight up, smoothly, with an easy button, making little noise. Adjusting from the sit to stand and vice-versa - including monitor adjustment - is quick. I wasn&t necessarily looking for an electric-powered option, but now that I have it, I&m glad. 4. It&s sturdy, and CAN actually hold all the weight of the monitors, arms, coffee/water bottles, and all the miscellany I wanted to pile on the monitor shelf. This converter is rated at 55 pounds; many others are rated at more like 20! 5. PLENTY of room for ergonomic keyboard & mouse. 6. One potential ergonomic downside - lack of a tilting keyboard tray - I solved by buying a Microsoft Sculpt ergonomic keyboard which fits splendidly on this keyboard tray and has a built-in prop to tilt it back. 7. Keyboard tray is only 1/2 inch above desk surface - others are raised up 1-3 inches which is bad for wrist ergonomics. A "drop keyboard" (available on some expensive converters) wasn&t an option for me, as those keyboards block off the entire upper row of drawers if you have a traditional desk. If the keyboard is still a bit high-ish for your wrists and you don&t have an adjustable chair to compensate, try buying the mat to prop up your chair (see below). 8. Affordable. 9. Easy to put together. 10. Not unattractive. 11. Cable-routing solutions. 12. I am also in love with the Flexispot mat - the wide one with bumpy feet on the sides. It is very comfortable in the standing position - you can just stand on the flat part or you can spread your legs around to touch the textured features such as the foot bumps. I then turn the mat over when in the sitting position, and its very thick size props my (non-adjustable) chair up to the correct height for my wrists on the keyboard. As a result, I didn&t have to buy one of those expensive adjustable chairs; was able to just use the chair I already own.

Best Purchase
I have wanted a lift desk for quite some time but my previous work station would not allow for the use of one due to cabinetry above my desk. Now I have a new employer and a new work station, so I finally broke down and bought myself the Motorized AlcoveRiser EM7 - 40&& and I love it. The motorized lift is wonderful. This allows me to stand and stretch instead of setting at my desk all day. I would buy it again and again. Best purchase of late.

Good riser--check your desk and make sure the riser works better than a full desk replacement
The product itself is great. I&ve only had it for a couple weeks, so it&s too early to be able to say whether the motor lasts a lifetime or not. If you&re looking for a sit/stand add-on to an existing desk rather than a complete desk replacement, do make sure that the desk you&re using is sturdy/stable enough to hold an additional ~40lbs or so. I get a wobble when using this elevated, but the wobble is in the desk itself, not the riser.

Motorized AlcoveRiser EM7 - 40" Review
I chose the AlcoveRiser because it was one of the few electric standing desk converters that lets me use my laptop and not just a mouse and keyboard. It was a great value, arrived quickly and easy to setup.
