How is this different from the spin cycle in your waching machine? It looks like just a spin dryer with some sexy marketing.
Yes, more spin = more wrinkles.
Assuming you're trying to save electricity over a regular tumble dryer (condenser type), the real way to get drying for less is a heat pump dryer. They work basically the same - circulate air in a closed loop, heat the air, blow through the drum collecting moisture, cool the air to release the moisture, heat the air again, etc. The difference is, the regular tumble dryer uses a regular element (like a heater/hair dryer/kettle) to heat the air, while the heat pump dryer uses, well, a heat pump. They typically use 1/4 to 1/3 of the power of a regular dryer. Cost more, but if you're a regular user, the savings will add up.
