In my experience not compatible with "Logitech Harmony One"

The rating refers to the article as it was sent by "vhbw".
The inscription does not look ready to move, Note regarding. Compatibility is "For 190304-2004" on the battery.
The battery can be dropped, but when placed in the charger in an error message ("Error loading" mutatis mutandis) comes.

Have for the first time received mail contact, with the question whether that article really compatible. There was immediate response, with regret, that the product was defective (I have not told), and it was immediately sent replacement, without that I had to send in the old.

As a replacement came the externally identical battery, which has the same problem. In the second contact I immediately offered to make a refund. The offer was gratefully accepted and immediately refunded the purchase price.

If you could not find more detail, there is a similar product, where the reviews turn out as well to the effect that the battery is not compatible. I then ordered a battery from another manufacturer (Battery-King), even if this good double costs there, but he works at least.

I spend at least two stars, as was at least very responsive and accommodating (but which refers to the dealer, not the article).
