Almost great....
Where the stitching is to close the strap it's so sharp I had to put paper tape on it to stop it from digging into my skin.  Also the hook closure is not comfortable at all.  But it's half the cost of a polar strap so... Decide which is more important to you.  Cost or comfort.  If it's cost, buy it.  If it's comfort, order the polar strap.
