Grrrrr, okay my irritation is that someone would tell you not to take the vest. First off, what good is life it you can't move around a bit. If you are talking about flying, take it, but get a letter from your doctor and have the Travel agent let the Airline know you will be carrying this device and it CANNOT be shipped. If you are talking about the newest vest :104, its size is to make it moveable. If you have the last version 103, I can tell you, get a luggage cart on wheels and take that sucker along. I flew to Las Vegas six years ago w/the 103, the machine didn't fit overhead, but the flight attendants worked to find me a spot for it. It hurts my heart to see that someone wouldn't go because of the machine. I wouldn't for any reason ship it, if you fly from NY to Cal, and in shipping it gets damaged what do you do when you get to CAl. call for a replacement. Don't take no for an answer.. this equipment is a lifesaving device. 9/11 or not, you deserve to take that machine on board. I am looking at going to Europe in the future and plan to take it. I will come down from my soap box now!Oh if you are traveling by car, there is no problem. I even found businesses will let you plug in outside the buildings for you to do a vest. From MN to Georgia, we stopped at a Restaurant, Two Rest Stops, a Travel Center, a Firestation, these were with the 103, I did my machine right from the car. I even found a place in the Anchorage airport to do my vest.See, it can and should be done. Travel, life is to short.
