The travel immersion heater does what it was created. He heated within about 5 minutes on a cup / glass of water, so that you're on vacation sometimes can fix by making tea or coffee itself. It is packaged in a small bag and fits virtually in every case, without further attention. Also not very difficult. The cable is not really long, but there are in each apartment with an outlet safety in accessible height. For me, absolutely not an obstacle. Price / performance ratio is great. I can make no statement about the durability of course currently.
