Query: A very good product

I am almost completely happy with this intercom. The only problem is that you are very tempted to speak right into the speaker and if you do, your words come out very muffled and the other person cannot understand you. You have to speak at least 6 inches from the speaker and tell the person on the other end to do the same. If it is used in that manner, it works perfectly fine.
