Unitron just came out with a smaller model Passport Moxi RIC. It’s called Passport Moxi 3G. I’ve been told that there is no difference between it and the Passport Moxi 13 RIC other than the smaller unit and therefore more cosmetic appeal and the battery which is smaller. Since I am still in the trial phrase, I could switch to this aid if I liked. I use a size 13 battery with the Moxi 13 which gives me long battery life. I’m wondering though if I should go with the smaller unit because A. It’s cute 
and B. It’s newer. 
Is it always best when the price is the same to go with the newest model?
