A detective kit that always appeals to children ... it remains that this product is very "cheap". Everything is thrown loose in the carton. A small storage suitcase would have been welcome. Do not expect to see anything as bad in plastic binoculars, one hardly sees through. An earpiece of the headset from the amplifier is off after 10 seconds. The three batteries of the pen, as opposed to what is stated, are not provided. It certainly can not also be specified as LR44, much too broad. We decided to return this product to Santa.
