bad buy purchase driver update $49.00. after filling form my credit card info slim driver pop up.I don't want anything else but one yr. driver update.they never gave me any comfirmation number or chance to use the special coupon @19.95 so please cancel everything but driver update for one year and its not working right right now

Dangerous Most of the updates suggested led to performance issues. Ultimately, I had to rollback the updates and restore to pre-update status. So please exercise caution before you go ahead with the updates suggested by SlimDrivers

Fantastic I took fear when I updated drivers in 2 laptops with the tool iobit updating drivers, and had to restore one with a point of restoration and other one with initial instalación of factory. The laptops are Compaq presario cq60, HP Pavilion dv7 and Asus Eee PC 1005PXD. Many thanks

Worth the price I use this program all the time. It never gets all the drivers and often gets the wrong ones. But it does whittle down the number of drivers I have to find by other programs/websites.
