Complete and utter waste of money. I made tea twice while on a trip and then it stopped functioning. I had one years ago that worked forever. This item was junk. Due to the low price it isn't even worth my time to return the faulty item. Don't waste your money or time on this item. Unfortunately, none of the immersion heaters on Amazon got good reviews. This one was better than most so I took a chance. I should have listened to the reviews because I didn't get lucky.
