The Isolator: the latest rip-off?

I don't even know what this thing is, but even if the parts only cost 5 cents, if the guy spent an hour putting it together and add in the time and materials for packaging and shipping and the time and cost of marketing and some profit AND it is effective; then in the overall scheme of things $150 is a bargain.

BTW what is it?

"Snake Oil, Ya'll" Steven Earle

On Jay Leno's show he joked about the price of a gallon of gasoline at the pump in Venezuela. $0.12
In the U.S. it it going up to $4.00
Like gasoline... make your own and it can be really cheap.
Have someone else make it for you and it WILL cost you a bundle.

Regarding price, remember it is imported and has the importers mark up added as well. To me, the main point about an accessory is does it work. If $150 materially improves the sound of a $10000 vinyl rig, surely it is money well spent. I note some of the replies have suggested a real improvment.
I tried a number of CD improvement mats over the years, Ringmat/Blacklight, I could'nt hear a thing. Being a sucker for strong reviews, I tried the much more expensive Marigo Stealth Signature. Result, a clear improvement in the sound and that is what matters.

It looks like the foam board that my firm sometimes uses when mounting presentation materials.
