Sometimes the reason we like certain products is their pure simplicity. At first you may believe this to be just a wrist band, in fact it also holds 'most Nokia' devices too. This is what the packaging suggests, although I am sure it fits most other brands of mobile phone too. When you are in the gym you often have no pockets in your clothing and dont wish to be carrying things around with wires trailing everywhere.
I use this wristband when at the gym, for either holding my mobile phone or my mp3 player. The soft cotton wrist band is quite attractive in black with bold writing of the word 'NOKIA' on it. The CP-218 will protect your device whilst you stay in shape, allowing you to listen to music and stay in touch.
The wristband is machine washable so you can thrown it in the wash with the rest of your gym kit as I do. At around a fiver it isn't an expensive piece of kit, but it has numerous uses and doesn't have to be used just for the gym. If you want you could use it day-to-day to keep your mp3 player safe whilst running the wire up your sleeve allowing for the discreet use.
The wristband is very comfortable, just like a normal wristband! Also, if desired it can be used as a sweatband if you so desire. Overall, for what is a simple design I find it very useful when at the gym and not many people have seen them before which did surprise me a little.
