How do you know its a different adapter, the one I got looks similar to the photos. Agreed it looks good for money, however you can stop the motors which can easily overload any adapter.
Came with a different adapter. Very impressed with the product and for £14 what a steal
Sounds like a good present for the mother-in-law
I recommend getting a car plug adaptor for the wall. It gives extra cord length, means you wont have to risk wrong settings on an ac adaptor, and is useful to have anyway.
