I've had my Casio Commando for about 20 days now and it seems to work fine.....except....I connected an older (2008) LG bluetooth to it. It worked fine for a couple of days and then I began to lose about every 3rd word of a conversation. People can hear me fine, but I lose about every 3rd word. Ok, old bluetooth+new phone= issues. So, last Tuesday I bought a brand new Jawbone Era and paired them. No problems, worked great Wednesday and Thursday. Friday, we went back to the same ol same ol--I'm not hearing but about 2 out of every 3 words someone speaks to me on the phone!
