At first we liked them. The range was excellent and they were easy for our two boys (4 and 5) to use. Unfortunately one of them stopped working after about a week. No charging or even trying to swap out the batteries didn't help. Most of the time it won't turn on. From time to time it turns on briefly, then immediately turns off and won't turn on again. We were very disappointed as they were a birthday present for my 4 year old son and he loved them until they stopped working.
