It brings ultrasound frequencies down to human range.
So you may hear the sound of bats and more.
The kit is very easy, good schematics, no soldering, 2 screws and few connectors. Just plug the connectors and you ready to go. I suggest to inspect visually the board and cables , because sometimes they are damaged. But if you have soldering skills its easy to repair. Fun to play and discover the secret audio range that is there, but we can't hear it. Until now :)

its doing its job well
Pros:
Ideal for small office, small hotel, home.
Ive using it with 1 co line from pstn/adsl router, and 2 co voip lines with cisco spa 112, it working perfect, caller id via voip lines have no problem to show up. Fax T38 working fine too.
Not to difficult to configure it, I write the commands on paper then dial all the commands at once.
Its very flexible with many configurations.
Caller ID working very good showing internal and external numbers.
The call waiting music is very good quality.
At power loss it keep the 3 co lines connected to the first 3 internals.
Different ring styles on internal and external and doorbell witch is very good future to have.
Easy to transfer call to another internal or fax.
Many many good stuff :) i cant write them all here.
Good quality plastics.
No problems so far.
Cons: It have blue light that indicates its power status, i prefer green color, but its just my preference.
ps the isdn splitter box in picture is resoldered to be used as rj11 hub, my setup is pstn and im not using any filters because the phone line from the router is voip.

Everything fine, except fingerprints on glass.
