I purchased this product over a month ago and was very pleased with the seller and the product! It arrived very quickly, was well packaged. The added bonus was that the product was in like new condition with original box, installation guide, even the warranty card.
I'm extremely pleased with the product and the Seller.

5.0 out of 5 stars Love Potion No. 9 April 1, 2012
By Julian
I bought this MAC OS 9 thinking that I could install it on a G4 that I was told I needed to better manufacture my product. However the G4 I bought was too new an edition to support the software. But from everything I read on the package, from the voice password capability to the Sherlock 2 features, I can understand why this version had such a following.

The box I bought had all the original update coupons, and appeared to be in full compliance with the user license agreement. I would have been very comfortable had I actually been able to use the software.

But I did not have any trouble re selling it, or the G4 at that.

This speaks volumes of the system, and based on its following I give it 5 stars.
