Anyone with Nooelec SMArt?

If you have a SMArt, have you noticed any performance increase or descrease?
Versus an established setup?
I’m seeing quite a few anomalies with it, and can’t explain them, so would greatly appreciate any input.
Many thanks.

Many thanks for replies!

All correspondence will be treated confidentially, PM me if you wish, and if you have a SMArt and experienced anything different after changing over from another receiver.
I did comparative testing vs 5 dongles and got results, but want to see if it’s only me.

Thanks,

Akos
