My one is sx 1888 v12, this one is work good, for 2 weeks at least.
Parcel came after almost 2 months (first shipment was claimed by customs (as seller said to me)). receiver came in non working condition, seller stated, that my old setup (SX1718 V10) can't work with new receiver (sx1798 V11) which is bullshit, I have connected everything correctly, but receiver did not connected to remote (new remote connected to old receiver with no problem) Anyway 25 € loss for no more that another remote...
