I must say, after running a 5555NII since July, it is one of the nicest radios I have ever run in the truck! The controls that you normally use are well laid out, the display is excellent day or night. The RX with DSP is great. I get many unsolicited kudos on the AM audio (Astatic 636 with a touch of echo)!
As far as the perceived drawbacks.............
1) Mic connector-easily remedied with a $20 adapter that is readily available from eBay,Stryker,Walcott,etc.
2) Menu driven radio-for those that shy away from menu driven radios, this radio once you have talk back, mic gain, echo etc. set, is very easy to operate while driving. Changing channels is a snap. Nice and positive with NO skipping! Band change is a nice decent size button. This radio is much easier to operate, IMHO, than a Stryker 955 with all the controls shoehorned on to the front panel!
3) My only caution is when you slide between channels using the VFO feature it will mess up that channel that you were on, unless you put it back where it belongs when you are done. Minor detail!
I took the radio out of the truck for the past week so I could take the 6666 out for a spin. My 6666 is a great radio, although she's tuned a little hot! Swings almost 100 watts AM/SSB! The small controls made me miss the 5555NII! And I had to put the WM DSP speaker back in the truck! One you go DSP there's no going back!
Again, as I've said before, at this price point you can't go wrong! Anytone has produced a winner!
