Our then 3-year old loved (and now 4, STILL loves) this thing.  The battery lasts surprisingly long.  The sirens are very real and accurate sounding.  You will find yourself tiring of this toy long before your future fireman does.  It was cool for Halloween/trick-or-treating since it lights up.  It attracts a lot of attention...which depending on the shyness of your child could be a good or bad thing. The little plastic piece covering the light did crack off after a few months (of HEAVY wearing time) so I can't really knock that, but it is what it is.
