These things are horrible, I don't see how they received any good review. First, as soon as you turn them on, STATIC!! Wow, the static makes these things useless, you cannot hardly hear anyone over the static no matter how close together you are, also, they didnt seem to go through a single wall in the house. Junk! Spend just a little bit more money and you can get some walkie talkies that have a range of over a mile! I thought these would just be easier for my 4-year old to be able to operate. He can operate them just fine, now if they just worked! Stay away!
P.S. I realize I may have had some interference of some kind, so I unplugged anything that I thought may be causing the interference and to no avail, these things are horrible.
