Supper simple installation and works perfect, no complaints! replaced an add on unit and got rid of all the extra plugs and connections that made my radio transmissions scratchy.

I buy these intercoms during almost 20 years for my projects and my fellows projects and never had any issue with them. Easy to install, comprehensive user manual, very good vox, its definitely No.1 for the money.

Ok I just received the Intercom. The description said it was a kit except there was no wire included and each of the connections has to be solder in by my mechanic. So now I have to spend about $300.00 more to have my AnP guy get wire and solder the connections. Shirley some of these connections could be presoldered. I sure hope it reduces the noise in our headsets or I will be really disappointed.
