Review: Bargain price for so much technology - Really pleased with this radio albeit I struggled with the multiple options in the instructions. Helpful videos online assisted. Good battery life and USB C charging help to make it my favourite radio.
Review: Solid and versatile little radios. - Solid radio that is pretty easy to program, with some excellent features. We use them on our licenced business frequencies, but you could just as easily program them for 446MHz or if you’re a Ham, set them up for amateur DMR. Shame there’s not a usb Port on the battery so that they could be charged independently of the radio, but that’s not a deal-breaker. I ordered some spare batteries and handheld mics direct from Radtel. Also swapped out the antennas for ones cut to our specific frequencies. Radios work very well and have good audio on both analog and digital. Recommended.

### ⭐⭐⭐⭐⭐ Exceptional value and quality
*by S***. on 22 July 2025*

I bought this radio not knowing what to expect when it arrived and I was amazed with the quality for the price, it feels really sturdy and has a reasonable weight to it, I am also amateur radio user used to different radios and this is as good as a more expensive radio, setting up the radio is fairly easy once you read the instructions and watch a couple of youtube videos, overall price and quality are exceptional and would buy from this company again.
