Sturdy (see recommendations). Well designed and built.
VERSADESK 48 Inch Electric Height Adjustable Ergonomic Desk ConverterGot this desk riser to address back and shoulder issues. Positive change has begun.The unit comes essentially fully assembled. No tools needed to attach the keyboard shelf. The unit is also includes attached felt pads to protect the surface of the base desk.SAFETY SUGGESTIONAs I was putting the workstation together, more than once I had my hand on the unit for balance and it “slipped”, once VERY close to falling off the main desk. Here is my recommendation: Swap out the felt pads for Non-Slip Rubber pads. I did this and now the desk extender is now rock solid. NO slipping and over all improved stabilityAlso, as a sharing, not a problem. I will be converting to a smaller footprint wireless keyboard and mouse.

Some issues, Works Well (36 inch versa desk)
I waited to own this 3 months before writing a review to see how it held up. I have a 3 monitor stand screwed into the middle stand hole and I am probably ~15 pounds under the weight limit for the 36 inch desk with this setup.Assembly: Easy, out of the box setup. Only adjustments needed are for the keyboard and plug ins.Sturdiness: It feels relatively sturdy, though as others have mentioned, the keyboard portion does lean forward a bit, even when adjusted to the tightest setting. I only notice this when I’m in standing desk mode.Quality: Overall, the quality seems good. I’ve been using this with my current setup for several months, switching to standing at least once a day, with no issues. One note: my up/down buttons are backwards. What the instructions said were up is actually down, and down is actually up. I still press the wrong button each time because intuitively it should work like how the instructions align it. I didn’t return to get a new one due to this, because I didn’t notice until I pretty much had everything set up, and it’s easy enough to deal with.Height: I am 5’4, and when I’m walking on my treadmill the tallest height is perfect for me. If you are taller than me and have something you’re walking on that elevates you a few inches, the height setting may have you hunched over. My base desk is relatively short, so if you have a taller desk that may help too.

When it works its great, warranty issues are a nightmare
The unit itself is very sturdy, however, when a part breaks getting it repaired is a nightmare. Within 3 months of purchase the motor failed and although they were going to cover it under warranty they wanted me to ship the entire unit, at my cost to them and they would return it, at my cost. The total bill was going to be more than a brand new unit would cost. After a considerable amount of time they finally agreed to ship me the motor and have me replace the motor and then they mailed it to the wrong address. Wouldn’t accept responsibility despite documenting they had the wrong address and I had to drive three hours out of my way to pick up the motor and install it. Fast forward to now, one of the ballbearing wheels cratered, see photo 1, causing the riser to roll off track and pop the brace off the riser itself, see photo’s two and three. No worries, its under warranty. Except they want me to pay them $150 to ship everything to me. We all know that unfortunately things break, but failing to price in contingencies for your warrantied product and expecting the customer to continue to pay you for your failed product is not acceptable.
