I did assume that it would be covered by my insurance but I was too weak and sick to make double sure.
Turns out that my Insurance only paid partially for the vest leaving me with an extra 700. a month out of pocket.
I was so ill that it took time for me to send the vest back. I was charged a whopping rental fee for not sending the vest back right away. Now, after having sent the vest back, the company says that parts are missing from the vest and that I should pay them almost 3k for the missing parts.
The vest itself is very uncomfortable and subject to malfunctions if I move and get the electrodes out of line.
