Things I liked: Feels great, great charging time. I bought this in order to have 2 batteries for my kid Pulse R73 but this battery last long enough.
Things I would have changed: The only bad thing is that you don't know when the battery is fully charged, have no indicator. That would been nice on the battery or in the charge, a light that indicate when the battery is charging and when is full.
What others should know: Very lasting battery.
