I've only barely used not used up a couple of the disks. I've found I prefer another system. The first $40.00 including priority mail shipment gets it.
Here it is with the exception that this one has 1" discs in addition to the 2" and 3". I think this version used to sell for around $70.00. Apparently they removed the 1" discs to lower the cost.
