Shure PGX24/SM58 Handheld Wireless System  

I have two PGX24/SM58 mics for my Karaoke business, and they take a licking and keep on rockin'.  They have been dropped several times with zero effect.   I have replaced the mic balls twice when dented and they look good as new. As for the battery cap, I have had no problems.  Now, if you wrench it down super tight, well sure...it's gonna crack.  I just tighten the end finger tight.  After all, it's not going to unscrew itself and come off.   Like many I was wary of letting the drunks use them, but after a year I let everyone use these mics.  Why?  They are super durable, easy to use and sound great.  I cant remember the last time I got out one of my wired SM58 backups. This mic also has a little known feature that I LOVE.  If you hold down the button at power on for 10 seconds, it locks the power button out, meaning that someone can't shut it off or mute it accidentally.  You know how people are.  Give em a button and they want to push it.  With this features, the mic stays on...all the time. Just buy one.  You wont be sorry.   

We have these at our church, we have had them for almost six years and they are still running strong! The only thing is after a few years the battery cover start to break off but with a little duct tape they are as good as new!! Will buy again in a heartbeat!

Hey, DS from Canada.  I think the blinking light is telling you that you have put the mic in a mode designed so the soundman can keep the talent from turning off the mics accidently.  Check the manual.  I think it has to do with how long you hold the power button down.  In my experience, this is a GREAT feature, not a problem.

We were using a mix of "economical" Audio-Technica wireless microphones.  We constantly had issues with signal loss, interference and dealt with regular poor battery connections in the transmitters.  We needed an improvement, but still needed to watch our budget.  So we bought 2 PGX series with the PGX1 transmitter for lapel mics, since then we have bought 3 more PGX series with the PGX2/SM58 mics and will be buying 3 more sets by the end of the year.  This product is easy to use, easy to setup, and the batteries are posted to last 8 hours, but with my own battery test I got about 12 hours before the batteries went low enough to turn the transmitter off.  I did find that if you are buying the handheld mics, it is cheaper to buy the transmitter and receiver separate than together.  Shure has great Customer Support and offers custom channel selection based on your area, though the Automatic Channel Selection built into the receiver has never given me any difficulty.
