These walkie talkies were a gift for my 10 year old granddaughter. From the minute they were unwrapped, she has loved them! She and her 2 neighbor girlfriends have been using them the last month. We have been impressed by the long distance they work. Her 7 year old cousin loved them so much, his mother got them for his birthday too! Do not know about battery life yet.These walkie talkies have lead to hours of fun for my daughter and her friends. However, they are not as durable as I would have liked. Part of the front of one of them was lost on the first day of play. Then one of the spots to clip a lanyard to, broke. Worst of all, one of the battery packs fell off (in tall grass) and was never found again. So, we are down to two working units instead of three. Furthermore, the instructions on how to use them were difficult to understand. There were a few times that they accidently got locked in a particular mode and it was challenging to figure out how to restore it. It was obvious that the person writing the instructions was not fluent with the English language. If you've got kids that are gentle on their toys, these are great. If not, look for something more durable.What is like about these radio are. . The different color styles and they was very easy to set up. I bought these for my 9 year for Christmas and she was very excited to get them. The audio is very clear. I would recommend these to anybody that has kids that likes to play hind n seek.I actually got these so my daughter can call me during the night if she needs me. Baby monitors don’t even reach her room from mine. These are so clear and the battery life lasts a long time. I love that these come with usb chargers instead of batteries! We enjoy these day and night!Bought these for our kids. They had lots of fun until people nearby started using the same channel. They weren't close enough for their conversation to be audible but it gave concern that someone could be listening. Changed channels and haven't had the problem again, but now we will use them for emergencies only. Super easy to use and battery lasted hours with continued use.I got the 3 pack for my 3 youngest children. 4, 9, 10. My nine year old and ten year old are gonna be riding their bikes a lot this summer. When my four year old rides with them they just ride around the block. It has a 3 mile radius but the town we live in is only a mile long so I didn't need anything with a bigger radius. They feel made very well. Like the don't feel cheap at all. I love that their rechargeable. When my kids go out to play together, they leave one inside and take the other two out. It's very convenient and enjoyable for the whole family :) we'll be purchasing more soon, one for myself, my husband and our 14 year old. So we're all connected at all times. I'm a foster parent for the 8, 9 and 14 year old. It just makes things a little more simple :) just a click of a button and we all know what's going on and its useful for bike accidents and other emergencies.I picked these up so that each of my kids could have a walkie talkie they could use without the worry of having to replace batteries or losing the backing while replacing them (which I have had happen with other walkie talkies).The different patterns make it easy to know which child the device belongs to and the ease of recharging and the length of the battery life makes this a great product.My kids love them and we (parents) love them too. You can be a really good distance away and still communicate, the battery lasts a long time and takes a normal charger so god forbid you lose or break the charger you can easily use an old phone charger. Great quality, really nice designs.Me gustaron mucho, el verde tenía una marchita negra como de pegamento que le pude quitar nada relevante, a mis hijas les gusto mucho y tienen muy buena señal en cluster donde vivimos ya fuera del cluster a más d 800mts se pierde la señal por las bardas, pero lo quiero para monitorear a mis hijos cuando salen al parque a jugar y muy bien.Compre estos walkie talkies como regalo de cumpleaños de mi hijo de 4 años, le gustaron mucho, compre el paquete de tres pero uno de los tres no funciona el botón de PTT, solo sirve para escuchar, no se si alguien me pueda ayudar a cambiar solo ese equipo ya los otros dos sirven bien y sería muy frustrante quitarle a mi hijo los tres.En general bien armados, diseño atractivo y buen funcionamiento. Habrá que ver si durabilidad ya con uso constanteJusto lo que necesitaba para mis niños, excelente tamaño , buena calidad del producto.Increibles
