When I received this product (brand new and unopened), I went to use it and discovered that the bottle of cleaner was completely empty. It had evaporated! I tried to use my own isopropyl alcohol, and a Q-tip, to get it in the cassette head but it didn't work very well.I e-mailed the seller and never heard back!
