I don’t have time to take even a quick glance at this software; and I won’t have time until the weekend, by which time this giveaway will be over. As such I don’t have advice on JetClean PRO. However, I figured I should post about this even though I can’t provide any advice on this product.
dotTechies can make up for my lack of guidance and help each other by reflecting on the quality of this giveaway in the comments  below.
Related to with what I mention in dotTech Advice, I have no time to blog during the weekdays currently. As such, I did not test this freebie; I don’t know what version is being given out, if you can install at a later date, etc. All I know is this giveaway is 48-hours long; it started on Jan 18 12 AM (no time zone specified) and as such will end Jan 20 12 AM (no time zone specified).
