It works well. The complaints are ridiculous! Rated 4 out of 5 stars

It does it's job as advertised. The complaints that it doesn't come with a sledgehammer to smash the entire hard drive are ludicrous. It only claims to wipe the cache using DOD algorithms. The critics of the DOD method probably are reacting because there are even deeper methods available now. A good analogy is marketers know that they can increase sales if they give a low, medium and high priced option- even if they really only plan on selling one of them. The very presence of another choice wildly skews the results. I would very much like to see any of the critics actually recover any data from this and post and prove actual data recovery...
