Really Feel like techs care

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.

Pros:

It seems to work. Analyzes system fairly quickly. Does regular updates.

Cons:

It keeps prompting me to extend subsciption even after it is newly installed. It is annoying that I had to complete this review just to uninstall the product.
