CNET have published their review of the Helio Ocean “beginner” smartphone. ‘The identifying design characteristic of the Helio Ocean lies in its unique dual-slider system. You can slide the phone vertically to reveal a numeric keypad or horizontally to reveal a QWERTY keyboard. It's completely innovative, though it's worth noting that because the keypad and keyboard are on separate layers (with the display layer on top), you can't keep both open at the same time.
That said, the sliding mechanisms are solidly constructed, and they provide a very satisfying "click" when each layer slides into place. Of course, a triple-decker design does result in quite a hefty phone. Measuring 4.33 inches long by 2.20 inches wide by 0.86 inch thick and weighing 5.61 ounces, the Ocean is not a compact device by any means and may feel like a small brick in a pants pocket or a purse. That said, it has beautifully smooth, curved lines all around its oval exterior and a soft-touch rubberized shell that makes it a pleasure to hold.’
