Eva,
Can't help but wonder if the biggest difference in the trial is the fact that you do not have an incision/pocket where the battery is put in and attached to leads being inserted (many seem to have a lot of pain from that particular site).

Also, the trial is usually only a few days and leads/battery have substance/tape, etc. very securely are not given much time for moving. Seems like when surgically implanted; while waiting for leads to scar in; sometimes leads begin to migrate and are no longer where they were when the trial was in for just a few days. I would think the migration might be one of the problems encountered. Once they begin to scar in and not in the right place; not good.

Yet it seems if you are one who does all the right "BLAST" that Mark so often speaks of; Success!!! Of course; this is just my observation/opinion. I did have an unsuccessful trial. Never did the implant.
