Lack of dedicated on/off/volume knob (uses buttons instead)Charging station/dock to drop in radiosOverly complicated interface for young childrenMany of the Amazon reviews criticize the range of the radios.

Effective range is less than 1 mile

Great range and battery life too!

Pretty good range so far,

Good for kids use and short range stuff but not anything long range.

Great range when the xonnection works - but very finicky

Excellent range, sound quality, and battery life.

It's easy to operate, buty the range is poor

My family uses these when we are out with the boys in supermarkets or other places they may be out of sight.-Amazing range indoor and out.-Haven't heard any interference-Great for small hands-Not that heavy-Battery lasts quite wellWe put neck straps on them so they are not dropped and easier to carry.

In Mexico, the range still was not great, but we could communicate for a distance of 200-300 feet away

Great range (anywhere in our neighborhood).

These radios work very well and with good range

Good range/reception.

Great range.

Excellent range.

Poor quality hopeless range and battery waste

Great range and very clear

Work great and long range

Range is about 2 miles top in the city, I don't know how the 20 mile is rated, but it definitely doesn't work at our area

Good range and clarity.

Range was about 1 mile out only...kind of disappointed because of the short range.

They don't seem to hold their charge as well as those I have purchased in the past.

They work as you would expect a kids wakie talkie to work
