I haven't used this device for an extended period, but since there are no mechanical parts, I expect that it will last. We have been using a professional on hold service for many years at about $60/month. The box that the professional company gave us sounded great when customers would call from a Lan Line. But, when calling from cell phone the voice messages were lower volume and the music would sound horrible. Music keeps cutting in and out and sounds very staticky. So we decided to save some $ and cancel our subscription and buy this unit. We are using the default music and voice messages that came preloaded instead of doing our own music and messages.
Verbal Content – generally, you should use 100 words to make up 1 minute of content produced with background music. In other words, one to two paragraphs per minute. The topic can range from product promotions to general company information.

Of the 10,000 callers who heard hold music during their minute wait, only 13 percent dropped off, and more than half guessed their wait time was less than a minute. To take it a step further, the study's last group heard a mix of music and messages while on hold for one minute. Two percent hung up. Another 81 percent thought their wait time was less than a minute.
