The concept of "restoration" makes sense, but that's about it.
I've had a LP cleaned by Mr. Kirmuss at a show. While the end result did what's expected, it's not for everyone. Much to "hands on" for me, if you want to do the complete cleaning according to Kirmuss.
You don't have to do the multi-step process and just clean an LP like the rest.
If you have a lot of used LP's of questionable quality, along with lots of time to burn, it seems just as good as others for the price point.
