The question is, is it any good? The longer answer is slightly more complicated, and involves discussing the difference in price between this radio and other more expensive, but higher quality, radios. But i can tell you that a group of hams here recently purchased the Beihaidao DMR radio (also sold under brands like Tytera, KERUIER or Retevis) and have been having excellent results with them.
The hack has since been published in PoC||GTFO 0x10 (donwload site) with all the gory details that turn a radio under $200 into the first hardware scanner for digital mobile radio. For comparison, the cost of a Motorola MotoTRBO UHF XPR 7550 DMR radio can reach $800.
The MD380 is a fairly basic radio with two main chips: an STM32F405 with a megabyte of Flash and 192k of RAM, and an HR C5000 baseband. The STM32 has both JTAG and a ROM bootloader, but both of these are protected by the Readout Device Protection (RDP). Getting around the RDP is the very definition of a jailbreak.
Here in the US Project 25 (P25 or APCO-25) is a suite of standards for digital radio communications for federal users, but for state/county and local public safety organizations including police dispatch channels are using Mototrbo DMR digital standard.
How to install the Hacked Firmware for the MD380. ( Here is a YouTube Video on the Update Process to the Jailbreak of the Beihaidao Radio)
You need source code from https://github.com/travisgoodspeed/md380tools this download does not ship with firmware to avoid legal trouble. Instead it grabs firmware from the Internet, decrypts it, and applies patches to that revision. The output files have a .img extension when unencrypted, and a .bin extension when packaged for the official firmware updater.
Most radios use a serial interface for programming, however MD380 is native USB. Building a USB programming cable for your radio is as easy as soldering on the proper cable adapter. Third party cables are available from ebay.
