I wouldnt be suprised if this turns into a class action lawsuit against microsoft. Bless their hearts as they mean well, but this is CLEARLY a design flaw that is effecting hundreds (or more) users. It's pretty much guaranteed that if you have a designer mouse that it's going to break due to a poorly designed middle scroll wheel (cheap flimsy plastic). This is terrible as Microsoft has marketed their designer products as high end equipment (though if you are reading this support thread you already know it's clearly NOT manufactured high end but rather to break and force you to buy a new one #FailingScupltComboAnyone?)
Microsoft needs to address this flaw and provide replacements for the effected users if they want to handle this correctly. NO HOOPS to jump through, NO BS excuses, just address the issue and provide a solution to resolve it (at microsoft's cost!)
Had two more of these go in the past week alone. As a result, we will no longer recommend or sell the product to our clients. You know whose mice and keyboards don't fail? Logitech.
