Elimavi 2.4GHz UHF Wireless Microphone System XLR Mic Adapter Wireless Transmitter and Receiver for Dynamic Microphone, Audio Mixer, PA System.

We're a Classic Rock band. This is our first time into using wireless transmitters for our vocals. These units work extremely well. The vocals are clear, they work transparently in other words "no hum", the battery life is at least 4+ hours, and the range is at least 50+ ft from the stage. The packaging is nice also which we use as the units storage box. One nice feature is the ability for the mic to adjust volume from the unit itself. The sound engineer needs to be aware of this and set it to max when dialing in sound check. We have experienced no problems with this unit. 100% recommendation.

The Elimavi is a very reasonably priced unit and it does work, but when used with a Shure SM 58, the sound is thin and washed out in comparison to wired sound, and that's after considerable time spent working with our PA board. This unit would be fine for small application speaking, public address, etc., and it's worth the money in those instances, but it's not what one would want to use in a live band environment.

They work great, The only issue I have is that the power button tends to turn on during transit draining the battery.

Terrible build quality. Shoddy workmanship. You get what you pay for. My worst nightmare -- After using it only three, maybe four times, one of the 1/4 adapter plugs came apart in one of the jacks in my new Bose Pro/1 plus and the shell of the end of the plug is stuck in one of the two input jacks, so that jack can't be used with a 1/4 plug anymore. I can't get it out and can't get it fixed without adding at least 20% to the cost of the speaker because the entire speaker will have to be taken apart and it is not covered under warranty. The only bright side is that because the input jacks are dual xlr-1/4 inch jacks, I can still use the jack with an XLR (mic) plug. Hard lesson to learn, so be aware.

They absolutely do as advertised. I use a link out feature on my harbinger mls900 line array speakers. This little item just saved me about 10 minutes of setup time and the ability to place the pair of speakers farther apart than I normally would because of cable runs and taping down across traffic areas. There are several more expensive options to choose, but these for the price work for what I do.
