I Prefer the Astatic Brand Mic because the Sound Clarity and Tone Quality is always Outstanding! Also the Quality of the Coiled Mic Cord is a Real Plus for me as it Expands easily and Keeps it Shape. I've used Astatic Brand Microphones since the early 1990's and I've never been Disappointed. This is the First One from CB World and it Arrived on Time and in Perfect Condition and I Purchased it at a Great Price too!
great mic nice and sturdy and is better than the common stock mics that come with your cb nice weight I give it 5 stars
This is the best cb mic I have ever used. Crystal clear audio on several radios. You won't find better.
Astatic is the only way to go for CB mics. I have been using them for years and I am never disappointed.
