Bad experience for me also! Looses connection frequently, have to press 5 times on a button to take a command, after minutes the same problem happens....
Very dissapointed in 2 words!
Runs perfectly with dongle and Newnigma2
Range about 7m.
If that's not enough, look for "MOD Ketchuss".
An external antenna is used there. Then up to 10m.
Unfortunately, no TV programming function is available yet.
