Marlow Magic –
These walkie talkies are brilliant. We bought them to take on our narrowboat holiday, so we could communicate from one end of the boat to the other. They were also useful when crew members walked ahead to open the lock gates.This was our 3rd set that we have owned, and by far the best. We could hear each other clearly and the range was good. The battery charge lasted well and they were easy to recharge. Very satisfied

Robust walkie talkies, however not suitable for what we needed them for. The only downfall is the weight, quite heavy on the pocket.
Paul Armstrong –
Worked as described. Used across couple of km range effectively. Good value for money.
Paul H. –
Excellent , good size nice and clear.
Greg Walker –
Excellent coverage, sturdy and waterproof!!

They feel nice to hold and are well built. Whilst the instructions are mediocre (and written in Chinglish), the basics are easy to pickup. I’ve used many PMR radios over the years and whilst these don’t have many features, the vibrate option isn’t one I’ve come across before – basically if a radio hasn’t received any transmission for over a minute, it will vibrate as it receives one, useful to alert you on a loud site.My problem with these is that the microphones aren’t sensitive enough so in a quiet house they need to be on full volume to hear the other person comfortably and as soon as you take them outside it becomes hard, noisy environments you can forget it!

Robuste und qualitativ hochwertige Geräte zu einem guten Preis-/Leistungsverhältnis
Nach den versuchsweisen/testweisen nutzen von 2 Stück Retevis RB648 habe ich mich entschlossen den Pool von PMR-Funkgeräten um weitere 4 Stück diese Typs zu erweitern. Besonders die Robustheit der Geräte sowohl gegen Schmutz als auch Feuchtigkeit (IP67) hat mich überzeugt. Dank der 2 Stück PTT-Tasten auch leicht mal mit Handschuhen zu bedienen. Ebenfalls ist die Ladung der Geräte in der Ladeschale über USB-C als auch direkt die Geräte über den am Gerät vorhanden USB-C Anschluss möglich, was eine flexiblere Ladung nach Gebrauch ermöglicht.

canal 16 canal sécurité
le canal 16 ne doit pas être utilisé sauf en cas de besoin d assistance. j utilise le canal 10 et ça va très bien.La porté est encore bonne 5/5 a 2km. 2 appareils en utilisation, 2 en recharge. Mon épouse a une jambe cassée et pour le moment elle ne peut se déplacer. Je suis toujours occupé sur le terrain ou au garage.. elle peut m appeler quant elle veut pour l’assister. Bien plus facile que le téléphone et surtout plus solide et étanche. j’utilise aussi les talkie walkie à bord du bateau. Elle, à la barre et moi en manœuvre ou a l’ancre.
