MYB:Hi YMB.Try safeeyes.
I have using it for 3 years
Do you need to pay yearly for Safeeyes? Website shows US$ 49.95 subscription fee per year. It seems expensive.
KidsWatch Prof is one-time payment for 3 PCs at US$ 49.95. After the first year the Website Filtering component is renewable at an annual cost of $29.95. All other features are not subscription based and will continue to function forever.
KidsWatch is rank as #1 in http://parental-time-control-software-review.toptenreviews.com/ This website gives a comparison of the features among the top few products.
