iFrogz has made a name for itself with its colorful modular case designs, though its Treadz case may be an exception to that rule, coming, as it does, only in black. Featuring a thick silicone exterior with a distinctive tire-tread pattern, the Treadz has good shock absorbency, and is easy to hold onto. And, at $15, the Treadz is cheaper than many of other silicone cases.
However, the low cost means fewer features. The screen protection is weak; it consists only of a thin, adhesive film, and the Click Wheel is recessed, but not covered by the silicone. You’ll need to spend an extra $3 to buy a decorative sticker from iFrogz to protect the Click Wheel. The bottom of the case is open to allow you access to the dock-connector port. While the Treadz is a serviceable case, it’s among the most barebones we’ve looked at.–Dan Moren
