It works for 2-3 meters, provided the vertical orientation to the upper part of the body and the horizontal angle of detection in 90-100 degrees. Consumes 1,8-1,4 Ma alone, which is certainly a lot, but the AAA Metal-Hydrite batteries will allow you not to think about it. The detectors fully met my expectations. I recommend the goods and the seller.
Not quite yet figured out, but it works on Hurray! Loud! Signal Selection = several. I have a dog barking for now. There are no batteries in the set. . 3 PCs lot Finger and 1 tablet in the remote.
Delivery packing quality is excellent. The seller and the store especially recommend. Molodzi. Took their cameras.
I thought something serious, it turned out that these toys even the child will not scare
