Can also to still existing transmitter cloning.

Unsettled by another review, only a hand-held transmitter was first ordered and tested whether this can clone the remaining remote controls. After this has worked, another 7 were ordered that all function properly.
The transmitters come with pre-installed battery.
It is a multi-language and German instructions and additional German Quick Start Guide for cloning the transmitter on existing stations in, yet also an indication of the guarantee.
In addition, there is a instructional video on Youtube: foolproof!
Product neatly packed received on the next day after ordering. Fits in the mailbox.
