The green battery Frachtlok attracts two to three pendant high slopes and mountains, before it is then broken after a few days. The children are understandably very disappointed and me it is incomprehensible why Brio is not in a position to offer battery locomotives that are durable and come up the Brio-slopes. Perhaps we should think about the production back from China back to Denmark, with the prices of Brio enough profit should still be making.
For a battery-Lok keeps only a few days, there may be only one star.
Supplement dated 6 January 2013: now the engine of the third battery Frachtlok is also defective. The warranty period has not yet expired and I try to give the locomotive back. Supplement of 28 January 2013: of course has worked without any problems at Amazon, as always. I am going to the yellow "BRIO 33215 Railway - BRIO Frachtlok" procure and report whether the better. The reviews for this, not so pretty, Lok are promising.
