QFX M-336 Dynamic Microphone System

Package arrived today (12/19/16), fairly securely packaged. Box in a box, with Styrofoam in the product box. Package was undamaged. Setup was a no-brainer. Pop in the batteries, plug in the attached cable and power cord, and....VOILA! You have sound! For my own purposes, I use a USB mixer connected between the computer and a small KUSTOM PA-50 unit. I use this setup for online recording. I tested the setup to see if my voice would come through the amp unit. It did. The next test was to see if my voice could be recorded online. It could. Here's where it gets a little confusing. Both microphones are color coded. One has a red band, and one has a green band. Each has a power indicator corresponding to the band color. The power light on the transmitter is red, and the signal lamps are green for both microphones. Why not have a blue power light, and red and green signal lamps, matching the microphones? It would make a little more sense. Both mics work, that is the first thing I looked for. They both send signals to the transmitter. This was verified by testing one mic at a time. The corresponding channel came up when the mic was turned on. There is no way to adjust microphone volume independently. It's either both, or none. The microphones are best suited for low to moderate usage environments. I, personally, would not use them for a karaoke show. The plastic microphone bodies and battery covers would be history after the first drunk dropped the microphone, thus ending the show. Shipping was not what it should have been. The way I see it, Wal-Mart owes me a $2.00 refund because I bumped up my shipping to a two day delivery. I ordered these on the 15th. They were supposed to be delivered on the 17th. It didn't happen. The date was changed, with no email as to why. This is not acceptable service.
