Hi Crystal and welcome to the club!!
The audiologist do a get tutorial and it's very easy to understand. From my experiences, I have found that I needed to have it reprogrammed several times in the beginning. When you push in on the ear piece does the vibration stop or lessen? I would have your audiologist check with Transear about the vibration if it continues.
I get the most benefit while in quieter settings, I generally turn it off in really noisy environments.
have you put the phone up to the microphone or lay on your good ear and watch TV? I have found that I do not have to turn my head or say "what" as often as I used to and that's a good thing
As far as battery life, it depends on how often you wear the device, If I wear mine every day for 6 hours, then I have to change the battery every 4 to 5 days.
Have fun with it! Your good ear will probably be sore from continually plugging it with your finger
