IDK
I have a VNS & i wouldnt tell you to get one. I do have an older unit (3/3.5yrs old) but i hate it
I work in sales and it just makes things such a bitch with my voice. I did get some seizure reduction from it.....(like 2-4 per year to 1-3) but the stress i get from having my voice constantly change annoys me so much.
It has cost me so many job interviews, etc. It makes my blood boil.
When i got it put in, the RNS was the new thing hitting the block. I am not sure the particulars with it, but i can tell you if you get sides like i do and work........you will not like it.
I do work 40hr/salary inside sales position tho, if you are not working or have a profession it would not effect, i think your opinion wouldn't be as bad as mine from the side effects.
