Avoid !!
This product worked fine for 2 days . First one broke down followed by the other . Seller only offered a refund of £3.75 ! When challenged, they replied that a full refund would only be issued on me returning the item ( at my expense) to an obscure address in China - and only then after an inspection/test ! Not good enough. They finally offered 50% refund only after I insisted ( and only then to cut my losses). Avoid this seller at all costs .

Don't waste your money
Worked for 2 days then just stopped working. Lights flash suggesting something was working but no pulsing etc. And don't expect the instructions to be any help, they appear to have been translated into English by a 3 year old.

Instructions on how to use it.
I received package a bit late. On opening was surprised to see USB charging when instructions said use batteries. Also surprised that there was no instructions on what each level did.

You get what you pay for
Arrived faulty, the supplier sent a returns label no problem, trouble is not everyone has a printer or access to kne. The only way to print this label was to drive 5 Mike's to a post office that can print it. As they are quite cheap it would have been more expensive to return it.
