Effective & Attractive with Wireless Charging
Color: Blue, Color: Blue
This "valet" organizer, which is the first time I've heard that term for a product like this, is nearly perfect. For me, it checks all of the boxes and in a perfect world, I would have opted for a smaller piece with only three compartments for mobile, wallet, and keys.
It's well made and quite attractive, especially the blue (favorite color, so I'm biased). The only feature I'm not a fan of is how the removeable, wireless charging pad was implemented, which sits up on a small lip at a slight incline. However, I'm not complaining one bit as the wireless charging is great, and it's a differentiator that determines the value of the piece. I would have preferred the pad be built into the piece, however the angle of it does make it easy to grab opposed to using your finger(s) to pry it up.
