48k miles, 4.5 years, every time I fill up the Stove knob comes out and opens my gas tank filler.
I rarely use the side bags but have had a key cut for those.
I like the fact that I can put my gloves on indoors and then head out.
I like that fact that I can't drop the keys in the fairing.
I like the fact that I can lock the bike and walk away without having to take my gloves off and fiddle around to put the keys in a pocket, from which they may be stolen.
KiPass is a good security system.
Is it perfect, no.
Is it better than keys, even chipped security keys,... yes.
If it fails on you it's a PITA, but so is losing yer keys, or having them stolen, or dropping them in the fairing.
