Marware Sportsuit Sensor Case for Nike + iPod Sport Kit for iPod nano 3G (Black)

The best (2009-01-03) Rating: 5/5
This is the best item I've found for using other than Nike Plus shoes. You can easily change it from one pair of shoes to another. A real life saver. Works great.

Sensor fit is very snug in this case, which is good. You don't want your sensor going anywhere... do you?

Velcro stays very tight which keeps the sensor in place for accurate recording and communication to your iPod. I prefer this case over the hard plastic case that would spin around while I ran.

Best case for your Nike +iPod sensor... for non-Nike shoes.
Great Product! (2008-12-12) Rating: 5/5
I didn't want to spend the money, nor did I like the Nike Plus shoes, so this sensor case was an easy fix to use my Nike Plus. I've had it for a couple of months now and I've never had to worry about losing my sensor.
LOST SENSOR!!! (2008-11-26) Rating: 1/5
I hit my shoe on something during a run i guess and the sensor was gone by the time i got back. Crapy.

Little expensive for such a little accessory (with shipping). Works just like it says it does. Fits nicely on your shoe. Only issue I had was that I couldn't tighten my laces as much as my other foot because it got in the way. It works fine to keep the sensor in place. My sensor wasn't working correctly after a week or so, but it's probably just the sensor itself and not this case.

Only thing I might note is that you can get it at someplace like BestBuy without having to pay shipping. I just didn't realize until after I had already bought this. It works though.
