“I use this vest in the operating room while I practice anesthesia. I have to keep it on low to last about 7 hours which is usually shorter than my day. I suppose that I should buy a back up battery. It makes me more comfortable than I have ever been.”
“Battery pack sticks out like a tumor. The pocket is on the hip, THE WORST POSSIBLE SPOT. I will make a new pocket further up and forward. Bought the mini battery, and it too is way too thick and sticks out. Poor design, guys.....GO BACK TO THE DRAWING BOARD. The vest fits well, keeps me warm, and I can use it with baggy jackets or alone.”
