"Probably the most annoying nagware out there"
It does check your drivers and let you download two a day.
If you don't buy the paid version it makes you wait 19 extra seconds for each download. The clock stops if you switch browser windows. A day after you install a driver a pop up window asks for feedbackm but the pop up window cannot be closed. You can postpone it for 15 minutes or one hour. How scummy and annoying.
