They just work.
You plug them in, press a button and they work. Simple.

Great solution
I recently bought these after finding out the hard way that two Tri-Band adapters could not be used in the same system. They work well for me, providing a practical solution for powering my rear channel speakers, while the Tri-band powers my rear heights. Both are used with Fosi ZA3 amps, which are compact and have an input sensitivity low enough that they work perfectly with the transmitters which have a max output of about 1.1 V which is very important to note. I would've given 5 stars except that the cords provided (3.5 mm x RCA) are way to short for this type of device that needs to be placed further away from electronics to avoid interference. Also, the indicator lights are excessively bright. These are really just minor inconveniences though. I hope this review helps others avoid (A) buying the wrong amps if you are pairing these with stereo amp and passive speakers, and (B) trying to use two sets of Tri-Band adapters in the same system. I forgot to mention, these are just plug and play devices and work exactly as they should right out of the box!!
