I remember it being purchased directly from the site you mentioned. It takes a very long time to heat up. The largest size sold on that site was probably 15x15cm, and it took about 10-15 minutes to reach 250 degrees from room temperature. Cooling down is another problem; it stays hot for quite a while after you turn it off. It's simple to use; you adjust the temperature up and down, press "set," and it starts heating up, and it stays hot for quite a while. There's nothing to cool it down with. I used it for soldering; yes, it's usable, but you can't adjust the temperature profile, so it's not a very practical way to use it.
