i have no idea why anyone should buy it if very similar lift made in Japan by Audio-Technica is much cheaper?AT is again making its own invention, with a simplification (the old 'lock-down' wire wasn't needed). When AT's patents expired, others rushed in with variations on the same technology; I don't see any of the knock-offs as being 'better'.
I had three AT 'Safety Raisers'. I didn't buy any, all came with TTs I bought. I sold one, lost another, now I'd down to one. Now that I use multiple arms, I regret my casual attitude.
