They sent me the wrong model, they sent me the correct model before I returned their product mark it refused me like they said in their email exchange. They are reactive and correct. I do not put the maximum score because the load is much lower, lower at least half the original panasonic battery and it is not stated in the presentation. However I put their average because it is operating normally and for the price it is worth it. We should not buy it thinking he even possibilities. This is a backup battery.
