Radioddity GD-77 Dual band DMR hand-held radio

A brief run down on the new radio as it arrived today - compared to the Retevis RT-82 and the MD-380 - programming, opewration and most importantly safety. I was a bit 'shocked' to find the radio shipping with a rather strange and non-standard USB adaptor, and one of the deathdapter 2 pin to 13A adaptors. How does it hold up - what are the good bits and the bad. To save you watching, it's actually very good value for money, and the negative points somewhat minor. Not in the video, but if you drop it as I have done three times today - the battery pack falls off - yet is very secure when on? Don't quite understand this at all? However - it's pretty tough as no signs of damage! Please forgive me at the end when I say CD, not GD-77!
