Granted not everyone will pocket carry their Nokia Lumia 900 Windows Phone. Some may prefer a belt case and if you like color choices, the Smartphone Experts Top Case is worth considering. It is a vertical case that rides comfortably on the belt and offers a modest amount of protection for your Nokia Lumia 900.
The Smartphone Experts Top Case comes in three color options; tan, black and red. The case's outer shell is leather and the Top Case is lined with soft felt. The case has just enough just enough padding to offer some protection without adding bulk.
The Nokia Lumia 900 is held in place by a single strap with magnetic closure. A stationary metal clip wrapped in leather is on the back of the case. The Top Case rides comfortably on the belt and the Lumia 900 fits snugly inside the case. The Lumia 900's square corners extend just enough to get a grip on the Windows Phone when you need to remove it from the case.
I wouldn't mind seeing the Lumia 900 sit a little lower in the case but as is, it'll do. Another change I wouldn't mind seeing is a wider belt clip. You do have a little wiggle in the case when it is on your belt. Not enough to make you feel as if the case is going to pop off your belt, but enough to be noticeable.
The Smartphone Experts Top Case is well made case. I've used similar with the Samsung Focus and Samsung Focus S and they've held up rather nicely over time. In using the Smartphone Experts Top Case over the past few days, the case does a nice job with the Nokia Lumia 900 and should hold up equally as well.
The SPE Top Case for the Nokia Lumia 900 is currently running $24.95 and you can find it here at the WPCentral.com Accessory Store.
