BONTEC Standing Desk Converter, 32in/80cm Height-Adjustable Dual Tier Workstation, Ergonomic Sit-Stand Desk Converter for PC Laptop Keyboard, Monitor Stand Compatible, Up to 15kg, Home Office (Black)

Very impressed with the build quality of this desk converter. A single page of instructions is provided, but it contains easy to follow instructions to put it together (which is quite simple).It's both heavy and big- good for putting a lot on it (I currently have two laptops and a monitor mounted via the pre-drilled hole), but it does mean that it's not really practical to move it around, if that's what you need it for.The mechanism feels really good- easy to lower or raise and the gas spring means you can set it at any height and it will stay in place- not just the maximum and the minimum.The biggest issue I've had with this is the depth- the upper work surface is 40cm front to back, which seems like a lot. The usable space is limited somewhat by the smartphone holder towards the front and the position of the monitor mount hole. This is only really a problem if, like me, you want to use a laptop connected to a monitor on a stand- in that instance, there's not enough space between the smartphone holder and the monitor stand to fit most laptops in. I solved this by removing the smartphone holder entirely (I now just have a hole which my laptop can sit over).

Really delighted with this product. Good sturdy build and easy to assemble. Exceeded my expectations given how cheap it was

Love this. I've been using it for the past two months & perfect for standing (I'm 5ft 5"). The hydraulics are great, easy enough to move up & down when pressed & folds away to width of approx. 20cm. Pads provided so wall/table is no scratched when using, or stood when folded. Great value for money.

Great product, sturdy and strong, great for converting desk to standing desk without the expense, mechanism is smooth, easy to switch between sitting and standing throughout the day

Love this new desk set up. Easy to put together. Loads of space for large keyboard and 2 screens. Easy to reposition the height.

Great quality very sturdy. Simple latch that allows the piston to bring the desk up. Amazing quality for the price. Definitely recommend this to anyone who needs a standing desk.

Sometimes sit, sometimes stand, this is so easy to use and rock solid stable and so easy to adjust through out height range.

I've been using this for a few weeks now since moving to a standing only posture, and so far no complaints. The desktop size is good, accommodates both my monitor and bookshelf speakers easily. Construction is sturdy and the keyboard shelf is just about right (yes it would be nice if it was independently adjustable, but for the price and reduced risk of less moving parts, I'm happy). Assembly took a couple of minutes. I don't adjust the height much, when I do it's a little difficult to raise, but given that I have two sets of speakers on it, maybe that's not too surprising. All in all, it meets my needs well, and a good investment in my lumbar health.
