I've used my Z Force with Daydream. It works pretty well. It does get hot, but doesn't seem to be a problem. Only odd thing I've noticed is occasionally it'll tilt a little funny. I've started taking more photospheres when I travel, so I can re-experience places later in Daydream. I can definitely spend longer in Daydream vs Cardboard without it bothering me (I start to feel "off" after about 15min in Cardboard, where I can spend 45min in Daydream and maybe just barely feel odd.)
