I reviewed Unlocker 187 and deferred
I am pleased you have found an Eraser alternative that you like and trust. I personally believe Eraser, especially V6 will be the industry standard, free and open source.
Honestly, when V6 is released there will be so much peer review I doubt anything will come close to Eraser but I am a little biased ! Joel is one of those “gifted” people who I believe will deliver the goods.
Perhaps when V6 is released you might like to invite the writers of Sure Delete to comment on V6 or perhaps say why Sure Delete is in any way better.
As I say, whatever program you decide to use for you data privacy I doubt you will enjoy the same feeling of security as Eraser users do.
Please keep checking back and as soon as V6 is released give it a try, you may be surprised !
