Query: Not happy with this product at all

Not happy with this product at all.. It does what its supposed to do I guess,but it's only good to be used indoors,if you want to use it while running,be prepared to lose it on the first day! Once you have it on your neck,its too short and the material to slippery so it doesn't stay put at all.. *VERY DISAPPOINTED*
