Had sena 20s duel set and seem to have set up spot on but made mistake of upgrading to 50s duel, seem plagued annoying little faults , wind noise from certain riders , connection gremlins , mesh intercom poor quality and other things (2021 gs , tft screen nav 6 , if anybody got ideal way to set up better) . Looking at comparison to cards packtalk some reviews seem to favour them , has anybody swapped to these or too Sena from cardo opinions would be grateful
