Il prodotto è completo Review Source RP Robert P. owner Real Estate Used the software for: Less than 6 months ### "Really Feel like techs care" August 22, 2021 5.0 When I encountered the issues that I was unable to repair (not able to access the site I wanted and my computer freezing after a half-hour of use or so) I contacted the System Mechanic help service. I connected with a very delightful young woman who was very able and willing to help. While the freezing issue wasn't resolved on the 1st contact, I immediately called back and reported it and set up another appointment for the next day. All told, the tech spent over 3 hours working on solving the problem and was very patient with this old, not computer knowledgeable old man. Considering the very nominal cost for the System Mechanic product, this one repair has way more than paid for itself... would recommend it to anyone. Pros It's a very simple process to keep your device running smoothly and fast. A simple download and then pretty much a series of clicks Cons After I downloaded the software, I was not able to access a site that I use every day... kept getting an error message to try again later, that the site was unavailable. It was not an issue I could fix myself. Review Source WK William K. N/A Writing and Editing Used the software for: 2+ years ### "Review" August 21, 2021 4.0 Pros It seems to work.

February 25, 2024 2.0 Pros Easy to use and seems to do a good job, but watch out for extra fees! Cons They offered a special and I extended my System Mechanic for a year. They immediately offered me another special, then another. So I took 4 special offers to extend my software for 4 years. However, each time I extended, they secretly signed me up for a $19.95 monthly fee. So I'm billed 4 X $19.95 / month for something I didn't want! I called and got the monthly fees stopped (I think), but I still have several months of payments that they took on my credit card, not reimbursed. Review Source LM Les M.
