spageGreat RadioReviewed on Jan 25,2025I had a issue with the programming cable and Retivis support reached out and sent a new cable very quickly. These are great little radios!Rusty WilliamsGreat Little RadioReviewed on Jan 17,2025This is a great little radio for the price. If you are hard of hearing, you will love this radio because it is LOUD. I have an external speaker plugged in, and inside my radio room I run the volume at 2 out of 36 and have NO trouble hearing it. Lots of information on the screen, but also lots of tiny writing making it hard for older eyes to read. If I was in need of another little dual band mobile radio I would not hesitate to buy another one.Joseph VanBlarganMy mobile radioReviewed on Jan 16,2025Love this radio and it was a good buy zero issues. I only disabled VOX after it came on one time. only complaint. probably my own error. other than that great radio. 50 watts and plenty of power in the mountains of Appalachia.Chris GriffithAmazing little radioReviewed on Jan 09,2025Just got it installed and I couldn't be happier with this purchase. Crystal clear audio, easy to program. Have not had time to make contacts yet so no TX reports but If it's like everything else I forsee no problem. I may be looking into buying more radios from this brand. This radio is awesome and the headset from them is just as awesome. I'm loving this brand.Jeff FroehnerAwesome radiosReviewed on Jan 03,2025Awesome radio! Easy to program and sounds great. Tried 3 radios from another brand and could not get to work. Very happy I chose this radio.AllegiA must get for dmr users who still use emulation!Reviewed on Apr 16,2024Overall amazing radio!
