Query: Scroll wheel doesnt work (also has no detent clicks)

After looking for a good corded mouse I thought this would be good, being a Microsoft product, but it is nice in concept, very poor in design and manufacturing. The scroll wheel worked for about 30 seconds, while feeling terrible (during the 30 seconds)and then it just stopped. The scroll wheel has no detents and is extremely still and hard to move without clicking. I bought 2 of these and the scroll was equally bad on both! One at least worked for more than 30 seconds, so I am having to return one. Try a different mouse.
