[RFI] Comments on RFI from Ductless Air Conditioning Units?

[Larry Benko]

100% agreement here.  I have posted this numerous times before and to 
everyone contemplating the purchase of potential interference producing 
devices WAKE  UP and write a REQUIREMENT THAT THE PRODUCT BE RF 
INTERFERENCE FREE into the contract.  If possible reserve as much of the 
payment until after installation and purchase with a credit card in case 
of a contract dispute.  I even do this for appliances such as 
dishwashers etc. at places like Lowes and Home Depot.  They sometimes 
need the store manager to initial this addendum to the sales agreement 
but they have never refused.

In my opinion listening to a similar product is next to worthless as an 
acceptance test.  The model you listen to might be slightly different 
from the one you might get and the installation might be significantly 
different from yours.

My $.02.
