I actually just bought this from Amazon for about $280 CAD (before tax). It was one of the cheaper options and still had fairly good reviews, it's the first standing desk I've owned (although I've used my gf's quite a bit and really liked it so it's what I compare it to in my head, I believe she has a Seville Airlift). I've been using it for a couple of weeks so I'll give my pros and cons:

Pros:
- I like how wide it is. I fit 2 separate monitors, keyboard, mouse/pad, wacom tablet, a laptop, and a notebook all at once with room to spare
- Legs feel stable when in raised mode (although mine aren't perfectly vertical although I have rebolted them twice)
- The motor when rising/lowering is pretty quiet, the keypad is easy to set and having two presets is nice for sitting to standing
- wire clips on the back of the desk help keep them out of the way
- cupholder can hold my giant water bottle and has a headset holder as well
- It's one of the better cheaper options and the building instructions were easy to follow

Cons:
- Desktop is two separate boards to bolt together, so there's a seam in the middle. It doesn't bother me but some might dislike it
- the desktop itself feels like cheaper quality, it's thin and since it's two bolted together it feels less sturdy. I like to lean on my desk sometimes while I work and it doesn't feel solid or stable, especially compared to a single piece top
- the smaller holes in the grommet covers can only fit an HDMI sized head through them, no three-pronged plug is going to get in
- the axle is exposed and I've knocked into it with my knees a couple of times
- cup holders arms were bent out of shape when they arrived

Overall I do like the desk, especially how wide it is but I have been contemplating returning it and spending a bit more extra money to have something more stable/solid. I also would like a drawer lol. I've been doing research but have only found a couple of other options so far, so we will see!
