Hello, Item received with 4 days late, good it was the holiday season, but it was not me who fixed delivery time. the battery label received does not match the site that has no mention made in china. It was to be supplied with a manual in French, it does not exist. Finally, the bill received no mention of the 2-year warranty. After exchange with the seller it confirmed to me by email that this was the case. So I installed and waiting to see his behavior (reliability) Sincerely
