very good and cheap Sport Armband for iPhone

I purchased the bracelet about 3 weeks ago and have been using it while cycling and jogging usually every other day for 1-3 hours. The iPhone 4 fits in perfectly. The controls (buttons and touchscreen) can be easily operated and the opening for the headphone jack is in the right place. The bracelet is comfortable to wear during sports, the iPhone will not get wet (from the inside) and even with little rain the Iphone stays dry. I wear it on the upper arm (jogging) and forearm (cycling). It keeps pretty good, only when driving off-road, the bracelet loose sometimes. The GPS receiver of the iPhone has so far always been good and the distance covered was correctly tracked (with Cyclemeter app). All in all, very highly recommended and also very inexpensive.
