Living in a mountainous region and thus saw the relief that surrounds me is rather to reach 1 or even 2 kms, but I think in plain or seaside it must be much more. I am very happy with this product I offered my nephews for Christmas and then I bought for my children. Very good listening and good grip. Recommend instead for "big" I will say from 8 years (calm versions). I think it remains a fragile instrument and I do not think it is not resistant to shocks or falls. In short this is not really a toy but everyone can spend quality time with. I recommend this product if like me you are looking for a friendly and playful device.
