Intriquing. But, as a responsible audiophile, I have to be concerned with the resale value of my investments. After a quick review and a failed attempt to find examples of used "fuzzy black strips" on A'Gon, Ebay, etc. it appears that there is a risk of losing up to 80% of this product's value once the seal has been broken. The thought of the potential embarrassment when I have to explain to my tweaky friends that I foolishly tossed real money at this product and lost a major chunk of my investment would make for highly anxiety, and sleepless nights. The cost of a single Margarita to settle my nerves would exceed the cost of the fuzzy black strips.
As much as I like to admit that any excuse to go to WalMart is a good one, I just can't justify the long-term value of this investment. Think I'm going pass.
But, wait, my wife just reminded me we can repurpose these in our motorhome.
