Phonak nano CIC

The “farmers fingers” is an interesting term. I am a Bricklayer, however I have not worked in the field for many years and as I stated in my post, I do believe that I have been very gentle with the Phonak’s. Is there an equivilent CIC from another manufacturer? I was told by my audiologist that the Phonak nano is the smallest CIC that there is.
Thank you
