alex323 @ I understand, at all so. The main question to include a stabilizer and did not work, if it is initially discharged? Because you need to check its performance.
I would at least puzzled seller about this issue, because I came to the stabilizer with a charged battery and it worked initially.
Another issue that Plavo correctly advises not to charge Stabia, and external charging and buy batteries separately. I did that on his advice and now I have a question a discharged battery in the camera Stub and do not care at all, you can shoot all day without stopping.
