There are 100s of reviews out their including videos etc. I\’m going to be very short. It\’s ok for the price If it\’s your 1st radio don\’t buy it without programming cable. Very hard to programme. If you have the cable and the Chirp software it works beautifully. There are 100 different models in they are pretty much all same.  It\’s all based on the same circuit and firmware some come with slightly more power. you are not going to see much difference. I bought the one for £18.99 It\’s fine works fine. Annoying it receives lots of unwanted signals. other than that it\’s ok
It doesn\’t work the same way as the Kenwood the d74e model but that is £500. If you have the right cable if you use windows 10 retevis cable seems to work fine. I wouldn\’t buy the cheapest cable.
