The only improvement that could easily be made and kept at or near the price would be a silent feature. I took care of it by turning off the speaker. I've used it on several frequencies and on 125 I've used it both encrypted and unencrypted. It's very easy to use. I don't think I've looked at the documentation other than to see if there's a way to turn it off. Cutting out the speaker was very easy and functionality was not compromised in any way.
