I was one of the lucky Moto winners, and I plan on doing an extensive review after using it for a month or so, but I'll give you my experience. I've always loved the whole idea of HeadBlades, and tried all the models. The original "push" model gave me too many cuts and abrasions; some of those cuts took quite a while to heal. The Sport was better, and the ATX was a definite improvement. Still, though, I tended to use a disposable because I was getting cuts in tough spots, like around my ears.
Enter the Moto. I really had given up on the HeadBlade, but I wanted to give it a chance, and it IS different. The blade end pivots a lot more, and I find the Moto essentially foolproof. I've used it about 20 times, with no cuts or irritation. It's not quite as close a shave as the original, but with the Moto, I can easily go against the grain, then with the grain, with excellent results. I couldn't do that with any of the other HeadBlades. The trackball is slick and glides effortlessly across the scalp.
The Moto is the best HeadBlade yet, and I have no reason to use any other headshaving method. And thanks again to Todd and Sly Bald Guys!
