The product is a good one!
Color: White, Size: 40inch without Power Outlet
The desk is conveniently assembled and looks nice. My daughter likes it.
One drawback is the corners of its top panel are a bit sharp and it would be better if they are rounded.

Choo Choo Desk
Color: White, Size: 40inch without Power Outlet
When looking for a desk; you're considering size and practicality for your purchase. Additionally, you're hoping the assembly of the desk will not require a brain surgeon to apply assembly. As this is my second Choo Choo Desk purchase; both the price, size, practicality and assembly are top notch. My wife uses one as her craft/sewing platform and the other as her computer desk. In placing both side by side, she can negotiate from one to the other with little to no effort and as it offers enough room on each platform with drawers for her notions, notebooks and patterns; She is quite content with her Choo Choo Desk(s) set up.
For those searching for a great desk, this Choo Choo set is ideal for minimum sized areas. One has a power bar with A/C and USB ports while the other is a simple desk corner to corner.

Good quality desk for the money
Color: White, Size: 40inch without Power Outlet
Overall this is nice little desk, cute, sturdy, and relatively easy to put together by myself. I took one star off because the bottoms of the desk drawers was missing. I contacted the seller and initially got a pretty quick response that the manufacturer would send replacement pieces and provide the shipping tracking information from the warehouse as soon as they had it. Then a few weeks went by without any word and I couldn't seem to contact anyone again (every link came up broken) so I thought I was essentially ghosted. But then they did contact me with the tracking information and eventually sent the replacement drawer flats.
So it took almost two months to resolve but I did get the missing pieces and overall I'm pretty happy with this desk as it was exactly what I wanted for my small home office.
