This would have been a good product, if it had better build quality internally. I performed the
trick, to great effect, a couple of times. Then I placed the device in a safe place, where nobody
even touched it, for maybe 6 months. Then I wanted to use it again - and it is dead, totally dead.
It simply does not charge at all, or something in the electronics broke - it does not matter, it
stopped working. I can therefore not recommend this at all. It is a good idea, it would have been
good if it was of higher quality - but it is simply unacceptable that something that is purchased
for this amount of money, and is kept absolutely safe for a few months, simply stops working.
