The acacia desktop is very nice. It's expensive, but unless you have woodworking tools and skills, or a nice table top to recycle, it's going to be hard to beat this. It looks like something that came from a furniture shop rather than an office supply store.
When built, the desk is a solid unit. No complaints as a user, except a note for tall people:
If you are tall, your legs may hit the frame on the underside of the desk when sitting down, as it runs through the middle of the desk. As a tall person I need about 45cm from the front of the desk to any frame underneath to avoid hitting it with my legs. The mounting position for Deskbird's desktops provides 33cm. With the current frame design, the only way around this is to mount your desktop with more overhang on the front edge than the back. The desktops that Deskbird sells only have one mounting position (threaded inserts for machine screws are pre-installed), so to solve this you'd either need to modify your desktop or buy frame-only and build a custom desktop that mounts in a suitable location for you.
Some feedback on the stand:
The individual legs are built like tanks, but the design relies on the desktop for its rigidity. The two sides of the frame are connected with cross pieces that are held in place only by the friction of machine screws pressing against their surface - tightened against powder-coated metal, which is a bit gross. A design where the cross piece was actually fastened to the legs would make the frame much more sturdy by itself, though this is mostly relevant to people buying a stand-alone frame and shouldn't affect buyers of desktops from Deskbird. Just know you can't really sit something on top of the stand by itself and expect to have a sturdy desk.
The included adhesive plastic cable management clips/ties are probably the weakest point in the package, though their use is entirely at your discretion thankfully. In my experience these tend to fail or turn gross long before the thing they're attached to has worn out. We used a roll of velcro cable tie instead (the cut-your-own type), which made a very tidy job without adhesives. There were plenty of places these ties could wrap around the frame or slide between the frame and the desktop. Only the length of cable from the control panel to the frame needed a different solution. I'd love to see Deskbird include a different cable management solution that didn't rely on adhesives.
The cable cover is also a little weak, but it's not structural. The outer edge of its slots are easily deformed by screws as they're very thing, and the cover may be resonant if you don't have it stuffed full of cables.
The USB charger on the side of the controls is a nice thought, but it's barely powerful enough to charge a phone, and a few of my devices won't charge off it at all. It's understandable with power delivered over UTP cable, but I'd say either do a feature like this properly or don't do it at all.
Overall I'm a happy customer, just a few nitpicks on the design.
