My wife got the KEY2 two weeks after I got the KEYone black!
So, my PRIV went for a swim leaving me in need of a phone. I tried to go back to my passport and for the most it was great but sadly the app gap was in full effect two years after it had been replaced by the PRIV so I went for the keyone black.
I knew key2 was on its way but I'd decided that from the pictures I preferred the keyone black looks.
My wife was very impressed with the k1 black too and she was eligible for update but I told her key2 was coming and she decided she'd gassump me and get that instead so here we are with one of each, both the black model.
My thoughts are the key2 is nicer to hold but they sort of remind me of Q10 (key1 black) and Q5 (key2) comparisons when they're side by side, the back of key2 is much better though with real "pips" of the bumpy variety as opposed to the flat "pips" on k1b.
Overall they both look great hers might be better though, if only just.
