"This item has a 4 page user manual & 3 modes of operation which utilize the same button but for different functions. On these grounds alone this product is rubbish there isnt a secretary in west capable of bothering to understand how to operate this. Great if you have an interest in techno-bloat-ware. After 1 day the LCD DISPLAY became faulty requiring a "reboot". The heater element is fast but the wizardry is ergonomically unsound."
