This adapter is used on a Z2 tablet. It is very effective and without reproach. It positions itself very easily by approaching the magnetic plug. Thanks to its magnet retention is correct but still avoid puddling the tablet while charging. The charging time by the system is not longer. Do not hesitate, this adapter will make life easier (no need to open this traditional door). The design is successful and the object weighs only a few grams. Negative: price but hey I do not regret my purchase.
