One thing is certain, it seriously compromises the more expensive kit out there at the price that it's selling. Even if you can't build it yourself, for a modest price Ecca has agreed to put them together in a nice tidy little box, I have his proto-type here and it's a great little box of tricks. It also stands it's ground sound-wise against my ESE / Atlantis / Quad GT & Magicstomp. OK some of those have other features, but if all you require are very accurate Shadows echoes, this is the only deal at the price.

I just want to add that when I tried it in the studio today, I used a Strat with the Ironstone pickups and it sounded just as good as the Strat with the Sliders, as it did when I tested it with my Classic Player Strat with the 57/62s fitted. happy days !
