Little pricey, but worth it
Very nice product. Creates a clean look on my fiances night stand rather than having everything all over the place. I like the little compartment with the door, its nice for putting things out of sight. The coin compartment is nice as well. The curve of the bottom makes it easy to get the coins out. I do think its a little pricey for what it is, but i still feel it was worth it to organize the clutter.

Nice touch
Allows for some organization, and looks nice. Pretty sturdy, and I have not had any issues with it, I was a little smaller than I hoped.
