sometimes it doesn't connect, quite often.
as far as I figured out, most often I succeeded if I turn on THR right after this thing, if the THR was already working, turning on this thing usually doesn't connect.
if you managed to connect them, jumping around with a tambourine, or some other miracle, it works more or less, switches presets and effects.
though while switching presets, it incorrectly reads the indicators of the included effects on the preset and some lights will be in the wrong state, e.g. I have the reverb on the THR is on, but the 4th light on this thing won't light..
and yes, I have latest firmware on the THR and this thing
I am returning it..
