Fast shipping. Two SL300 units varied in overall condition a bit, but vey acceptable at the price. Cosmetically, they were cleaned up nicely. Accessories and .3rd party batteries worked well. The master transmit oscillator was off 500 Hz in one, needing an adjustment with the Motorola Tuner software for DMR operation with a hotspot. Overall, very pleased. I recommended to others who had a similar positive buying experience. Oh, units would not take a firmware upgrade due to being locked to a n expired service contract at a radio shop. The Motorola CPS could not recover the radios to allow a firmware upgrade. A minor inconvenience. Both radios worked with CPS 2.0. Only one worked with both 2.0 and 16.0 Build 828. This was probably because of different firmware on the two radios. I was able to add custom audio prompts to both radios easily.
