I think it's great that there is an alternative to the outrageously expensive batteries and chargers from Canon. Unfortunately, there is a technical problem: The contact tabs of the charger are designed so clunky that insertion of the charged Batteries is very difficult without damaging the sensitive contacts in the battery itself. The first battery had already delivered a defect likely for the reasons. The supplier must therefore unhesitatingly given me a new set. After a closer view with a magnifying glass, I discovered the technical difficulty and the two loading tongues with a Fine tool "sharpened". Since then the battery replacement work in the charger "like clockwork" and I am very satisfied.
