A good locomotive, relatively powerful. With rechargeable batteries, this is a very good toy (if not, it is rather a ruin, because you have to replace the batteries after three four days of intensive use). The big problem is the remote control, which only works if we place a certain way, does not actually offers two speeds, fails to stop the train, nor do change direction (we do can not switch from forward to reverse, not manually). So it is a great toy in itself, but the remote is not very useful. My boys, however, were quickly stopped using it and control the engine manually.
