No it is not. Log onto eBay or Amazon and you'll find a real rechargeable hair dryer just launched by tek maker co.

I considered importing the Tek Maker dryer and thus had a sample sent. In my opinion the battery does not last more than about 12 minutes, takes hours to charge and is nowhere near as good in performance as the Ioneat gas/battery driven portable dryer found at www.ioneat.co.UK

gas? is it safe ?
