I love the functionality but the quality control and material used make it a poor choice

The functionality is great, but the product does not last and Microsoft refuses to stand behind this product.

so, I loved the idea and the functionality of this product WHEN IT WORKED.

Great functionality, look, comfort, connectivity

I gave it two stars because I like the functionality, but the reliability is horrid.

If you are a Runners World type jogger and don't plan to wear this 23 hours a day I think you could get years of use and the functionality is impressive.

Loved the functionality, integrated well with my Samsung phone.

Love the functionality and fit
