VIVO Compact Electric Stand Up Desk Frame for 39 to 80 Inch Table Tops - Single Motor Ergonomic Height Adjustable Base with Memory Controller, Black (DESK-E151EB) - Perfect for Home Office, Workspace & Standing Desk Setup

I bought this for my daughter for her birthday and purchased a living edge table top for it. It looks great. The things I like about the vivo are1. The mechanism that raises the table top is very smooth and even2. The table base can be extended to over 6. 5 feet long if the need arises for a bigger desk. That was one of the selling points for me. My daughter doesn't have room for a desk longer than 4 feet right now, but if she should move to a bigger office, she can just get a new top and keep the base.3. It feels pretty heavy duty. The pieces are made of strong metal and will likely last a long time.4. There is a collision detection mechanism that backs off a few millimeters if it senses that the desk has come into contact with something while raising it.5. It has presets so you can save your favorite heights if you use the same heights a lot, or if two different people use the desk. I can't remember if it was 3 or 4 presets, but I think that's a great feature.The things I didn't like as much.1. the extension bar was a little difficult to install when putting the table together and, in fact, I stripped the set screw while trying to install it the first time. (But the Vivo person I talked to was super helpful and sent out a replacement right away) One end is hexagonal (or octagonal, I didn't take time to count the sides) and that end has to go in first. But when you extend the other end (that is the end with the set screw) it doesn't really match up and you kind of have to twist it in place. I tried to twist it, but it didn't seem to work the first time and that is why the set screw got stripped, I was trying to force it into place. But with the new one they sent it was super easy and worked perfectly the first time. Not sure if it was me or the extension rod that was messed up the first time.2. Some of the screws seem pretty short for such a heavy frame. There was one set of screws that I think connected the cross bars to the legs, but I might be misremembering that, that were super short. I was really worried that they would give way too easily. The screws that attached the table top to the base seemed a bit short too, but that is likely because people use table tops of different depths. And for the table top there were several screws. I don't know if I'm just being extra cautious or if those really short screws are a problem or not. The table was lifted into a car, driven around in the car for a day, then lifted out of the car, and turned on it's side to fit through a couple doors and it didn't come apart. (My daughter did say she tightened down all the screws before she started using it.) And so far it's working fine so they might not be a problem. I just would have used longer screws.Hopefully it lasts a good long time. But I'm pretty happy with it now.
