although these are recommended for over 13s, my 11 and 6-year olds (I bought two -binoculars, not kids!) love them. At the price it's well worth them both having the same bit of kit - they can keep up with each other, and not fight over who gets to see what for how long. They are not too big for the six-year old, so ignore the 13 thing. Optical quality is very good. I reckon you'd have to spend alot more to achieve substatially better. P.S. we use them also for astronomy, so the Moon and the moons of Jupiter are excitingly clear.
