This is the second intercom system I have purchased from PCI, and I have nothing but good to say about both the intercom and the service from PCI. I previously installed a system in a sandrail and it really made the rides so much more enjoyable. It's pretty amazing how it cuts out the engine and wind noise; yet, it allows everyone to converse at a normal speaking level. Being able to add music via bluetooth is an added bonus. I highly recommend using PCI. Their service is second to none.
