I bought this switching from a flat earring tree holder. Read the dimensions as it takes up a TON of space. You may not think 7.5" wide is much at first, but that is a lot of empty space on your dresser. It's bigger than my lamp and certainly much larger than the jewelry box I have. It wobbled until I tightened it with a pair of pliers.

Pros:
tiny holes allow for studs to hold, even small ones
a nice distance between the holes means larger earrings don't require you to skip a hole
color is nice
some will like the rotating feature, obviously
the distance between bars is fair for longer dangle-type earrings

Cons:
the small holes require you to remove the backs from your hook earrings (the clear holders) or push them forward past the bendy piece
it is difficult to add all off your earrings when you have mostly these type earrings, especially if you have larger hands

Overall, it would probably be excellent if I didn't know I love my flat style holder... If only I could find a larger version of that! :)
