Ever since the first E30 series came along, BMW M3 has enchanted car enthusiasts around the world. The E90 series, that has been with us a few years, is no exception.

Easy to install
Size: 23.6 Inch, Color: White, Size: 23.6 Inch, Color: White
This product exceeded my expectations. The installation process was incredibly straightforward—even for someone with little to no experience—and the instructions were clear and easy to follow. Once installed, it feels very sturdy and secure, with no wobbling or shifting at all. You can tell it’s well-designed and made with quality materials. I also appreciated how quickly I was able to set everything up without needing any extra tools or help. Overall, it’s a reliable, user-friendly product that I would absolutely recommend to anyone looking for something dependable and easy to install. Drill is required though.

Don't buy
Size: 23.6 Inch, Color: White
The shelf is very flimsy and not sturdy at all. It feels unstable and poorly made. Definitely not worth the money, I wouldn’t recommend wasting your time or money on this product.

Looks Great with a Couple of Modifications
Turned out nice. I would say for the price, it's great quality and took about 45 mins to assemble, but I was also taking my time and using a screw gun. I wouldn't assemble everything by hand. Maybe to get the machined screws started by hand but everything else use a screw gun or drill. 1 thing to look out for: The light strip has a piece of it's stickers that is longer on the one end. I think that's so you can move the light strip over and then the end with the cord on it can be routed threw the top of the wooden side panel, then down on the outside of the shelf. As you can see in my video, I had to route it down on the inside of the shelf because the part that connects the power cord to the led strip landed right where 2 wood panels need to be screwed together. This might seem confusing in this review, but lay down the light strip 1st and then you might understand what I mean. The way mine turned out is still OK, but as you can see the power button control has to be mounted on the inside and you'll see it. Not a big deal for me, but that's not the way I wanted it to begin with. Also, I hated that the cord was white. I just put a couple coats of black spray paint and it looks a lot better.
