I fully expect the same result!I learned something new today... how to send money online through PayPal. I bought two of the battery extractors. I think they'll pay for themselves in removing frustration.
I've found a work around that sort of works. I turn the charger or the aircraft upside down, so that my thumb is pushing on the release button, rather than my index finger. It's a big improvement, but I look forward to having a tool that just makes it simple and easy.
