mikeMuch better range than I expectedReviewed in United States on Dec 11,2018Bought these for my kids and the kids next door got a pair as well. Battery life is fantastic. They have significant range. Our experience exceeds the manufacturers stated range. Isn't that unusual. They have held up for a half a summers worth of young teen and tween abuse and still look like new.Carlton A EllisGreat Value for the Money-Solid, Flexible, and Affordable!Reviewed in United States on Dec 11,2018Solid, flexible, and affordable! These little radios are a huge step above bubble pack consumer radios with great range and RX sensitivity, easy to program, have scan capability, good battery life, and easy recharging from any standard USB portChris JacksonSome of the best little 2-way radios for the priceReviewed in United States on Dec 11,2018I really like this little radio. The audio is fine - clear and crisp. As a single unit, the radio does not come with a programming cable, but the cable I buy from Retevis works great. The software is simple (Windows only) and very easy to use. Handy little transceiver - and it this price if you loose it - buy another! Recommend it for what it is - simple and works.Scott StaufferGet it!!Reviewed in United States on Dec 11,2018Got these radios for an event last weekend, and these did amazing. We operate in a hotel that normally kills signal just going down the hallway. I was able to leave, and still receive and transmit across the street! For only 30 bucks, This is a steal! They come pre programmed with standard stuff, but can be reprogrammed in less than 5 minutes with a Retevis style cable. Comes with everything you need to get started, even an earpiece! Uhf only, long battery life, and durable. (I dropped mine many times lol) Pros: Long battery life Good signal receive and transmit Durable Tons of extras in box Small price Cons: No screen, but a voice tells you which channel your on. It's not a dealbreaker by any means.Cathy RobertsThey work great!Reviewed in United States on Dec 11,2018These are great! We've already tinkered with them around the neighborhood and from our granddaughters home to ours. Can't wait till I get a chance to hiking with them.BackdraftGutes Semi-Professionelles FunkgerätReviewed in United States on Oct 25,2018Sehr gut verarbeitetes Handfunkgerät mit hervorragenden Leistungen. Auch für den professionellen bzw. semi-professionellen Einsatz geeignet. WICHTIG: Das Gerät ist lizenzfrei und nicht nur "EU-User" kompatibel ...Thomas D WintersFantastic ValueReviewed in United States on Oct 20,2018Now I was concerned at the price of these. Buying for use in a retail store where constant use and frequent drops would be an issue I considered spending more. I’m glad I didn’t. The radios are great. Really clear sound and ideal for a large store. The fact they didn’t need any programming was a huge bonus aswell used straight out of the box. Only issue is the headset. Good sound but after less than a month 4 of the 6 have packed in. Considering the price though it’s no hardship to purchase 6 higher end headsets. Would highly recommend.Cameron FranksGood walkie talkies -Reviewed in United States on Oct 20,2018Walkie talkies are good. Our children 6 - 10 ordered 4 and they arrived quickly. Two of them don't work on channel 1, but not a huge deal as we have 15 more to choose from. Biggest complaint is the very low quality headphones. Children were very excited about this feature and unfortunately they broke very quickly without too much cause. Update- Karen from their customer service team has sent us new headphones free of charge which are more robust and working well. Many thanks and good customer service.Achat vérifiéGlobalement satisfaitReviewed in United States on Oct 19,2018Ces terminaux sont préprogrammés. Pour qu'ils soient compatibles avec certains PMR 446 à affichage du canal, il faut connaitre le sous code CTTCS appliqué sur chaque canal. Aprèsl'achat, il a fallut acheter un cordon de programmation et télécharger le pilote usb/série et le logiciel adapté. Un petit dé-patouillage informatique car il n'y a pas d'aide, cela devient aisé. Il faut se munir de tableaux de correspondance des codes CTTCS car ils sont en fréquences et non en numérique. Il est possible de passer la puissance à 2w. Seul problème : la gestion du scan. La notice ne précise pas la procédure de mise en service ni d'arret de cette fonction, ce qui est dommageable pour une bonne utilisation. En effet, le scan se paramètre canal par canal logiciellement. Si un terminal est programmé sans CCTCS on peut écouter toutes les fréquences, san spour autant interférer (le code sera 0 et il ne sera pas possible d'enter en contact avec le correspondant).Achat vérifiéExcellentReviewed in United States on Oct 19,2018Mon enfant m'a demandé des talkie-walkie en cadeau. En achetant un jouet j'étais quasi sur de me faire avoir. Alors j'ai opté pour un modèle "semi-pro" en me disant que cela ferait un très bon jouet. Bingo ! Testé dans un immeuble d'une cinquantaine d'appartements, depuis la cave : impeccable. Ensuite depuis l'appartement (fenêtres fermés) vers l'extérieur (parc boisé et milieu urbain) très bon jusque 700 m. Après les interférences augmentent mais encore bon jusque 1km.
