Watching when ordering 2 Vaporizrn - note frequency !!!

Santa Claus brings our two daughters after tomorrow everyone a Happy People VaporizR NIKKO RC 35001 - VaporizR, land and water, blue. The eager elves (Mum & Dad) have in advance the batteries of cars charged so that the girls can chase away immediately after unpacking, while they did not discover the first test whether the carts are roadworthy that unfortunately both have the same frequency on the remote control & How exactly is the product information text (27 and / or 40 MHz) suggests it is possible to switch (by lever or knob) to another channel. Immediately have Nicholas' helpers Nikko (the manufacturer of VaporizR) contacted, which gave them the Council to exchange a car with a request to Amazon to take care of the inscription before sending, because: On the packaging of each dynamics cart is a tiny not too visible stickers indicating which band C or D, respektiv which frequency has 27 or 40 Mhz of car / remote control !!!!
So dear Amazon customers, listen to the counsel of the wise elves and fit on the label on the package to, otherwise you have to send them back as a VaporizR & Change ... Have fun otherwise by Raser ... are the elves and their Kids determined also soon have ... I thought follows after extensive testing between Santa & Christmas an addition to the review of the rating, plus & minus (if having) -points ...!?
