Query: Beware - when this product fails it can't be repaired

I was given mine as a gift. It worked for a while, but as mentioned in another review, the instructions for charging and recharging are fussy and need to be followed to the letter. When mine within weeks ceased to be rechargable any longer, I contacted the store, manufacturer, [...] and no one would stand behind this. Have lots of fun with it for the 30-60 days that it is likely to work properly.
