We have a panasonic and it has worked well with gluten-free breads IF you mix
the dough this way:  mix a batter in your mixer (we have a Kitchen Aid) with
the dry and liquid ingredients.  Put that batter in the bread machine and add
the yeast separately if your bread machine has a yeast dispenser. Then run
the machine on the basic bread cycle.  If you don't mix a batter beforehand,
 the rice flours won't mix in completely.
   Confession:  we've switched to Beth Hillson's Gluten-Free Pantry bread
mix, which is fabulous and you have bread in an hour.  Our expensive bread
machine is sitting in the pantry!
