    We have tested two RT4 and found that it is much faster than the 3G model. In particular, the GPS module gives accurate location. Will continue to try and send my review later.

    only got it today and as up to now I am well impressed with its size and build the keypad is still small like the inrico but not an issue great audio bought the cradle charger and speaker mike so easy to use in the car and portable would be nice if it had the analogue module on it but a great radio and phone

    I received the RT4 a few days ago, and wanted to note my initial impressions:
    1. The unit is very sturdy and seems to be well engineered and executed. The case is made of quality plastic, and the buttons are nice with good tactile feedback.
    2. The speaker and mic seem to be well suited to using as a handy talkie – the speaker can get quite loud, and the mic seems to pickup voice well.
    3. The OS and software are a bit dated, but usable – Android 6.0 was released in 2015 – but there is a recent update. The stock dashboard is ok, but it would be nice to have an HT themed/suited dashboard.
    Overall I am very please with the phone – my only reason for a 4 star rating is the OS.

    The RT4 is built like a tank. Very sturdy and hefty. The battery life is amazing at 4600mah. Easily lasts all day.
    Nice tactile feel to the buttons and the vol knob is snug.
    The display & popup keyboard may be on the small side, but it also helps preserve battery life. Overall it is a quality handheld and looks great as well.
