## Description

Product Description               Not only does this handy gadget screen telemarketing calls for you, it also helps to ensure they won't keep trying to get ahold of you. The TeleZapper from Privacy Technologies plugs into any phone or phone jack. It works by emitting a special tone that makes your number appear disconnected to computer-generated calls. Eventually, as your number is eliminated from lists, the calls become a rarity, rather than routine. It won't interfere with manually dialed calls, answering machines, voicemail, Caller ID or Call Waiting. However, it may remove your number from the lists of organizations that use dialer computers. Easy installation. No monthly fees or service charges. AC adapter and phone cord included. Charcoal gray. No. TZ 900. Imported. 3Hx7Wx5D".                  .com               When you've had your dinner interrupted by a telemarketer one too many times, treat your phone line and yourself to the Telezapper TZ 900. It's a simple, one-time-cost solution to the problem of annoying telemarketing calls. Based on the enormously popular classic Telezapper, the newer Telezapper TZ 900 offers the advantages of a slimmer profile, built-in battery power, and an advanced three-tone mode. Here's how it works: Given that more than 90 percent of telemarketing calls are placed with computer assistance, when either you or your answering machine answers the phone, the Telezapper emits a special tone that tells the computer your number has been permanently disconnected. Telemarketing companies that use automated dialing systems typically remove disconnected numbers from their calling lists, and as your phone number is eliminated from more and more telemarketing lists, you'll notice fewer calls. Of course, not all telemarketers use predictive dialing systems, and those that do will undoubtedly continue their work to evade the Telezapper, but it can be a partial solution. Most predictive dialing systems will be fooled by the Telezapper's standard single tone. However, for newer dialing systems (presumably designed in response to the success of the previous Telezapper model), the TZ 900 offers an advance three-tone mode. To change the mode, unscrew and remove the protective case and then slide a recessed switch. (We suggest that Privacy Technologies put the switch on the outside for their next model.) For the most part, regular callers are unaffected by the Telezapper, but it may "zap" calls from other organizations that use the same predictive dialing technology (such as charities, pollsters, and automated emergency weather systems) and from callers who use certain types of calling cards. (For more information, click FAQ, or frequently asked questions, in the left navigation bar.) Installation takes seconds. Just plug the Telezapper into your phone line and your phone into the Telezapper. It's that simple. A built-in lithium-ion battery provides power and will likely last for the lifetime of the unit. The Telezapper includes a phone cord and instructions. Privacy Technologies backs the device with a one-year warranty. --Mike BrownProsReduces telemarketing calls placed by predictive dialing systems Doesn't interfere with most normal calls Inexpensive, one-time-cost solution Extremely easy to install and use ConsMay "zap" some desired calls Annoying beep every time the receiver is lifted

                        From the Manufacturer               The Telezapper TZ 900 plugs into any phone or phone jack to "zap" many annoying computer-generated telemarketing calls. Just one Telezapper covers all phones and answering machines connected to that line. It won't interfere with manually dialed calls, or with answering machines, voicemail, caller ID, or call waiting. When you or your answering machine picks up the phone, the Telezapper emits a special tone that fools the computer into thinking your number is disconnected. As your number is eliminated from more and more lists, those annoying computer-generated telemarketing calls just about stop altogether. With the Telezapper, there are no monthly fees or service charges. It offers easy installation, compact design, and a one-year full warranty. Note that the Telezapper may also "zap" calls from other organizations that use predictive dialer computers, such as charities, pollsters, and emergency-announcement services.             See more

## Customer Reviews

### ⭐⭐⭐⭐⭐ It REALLY Works!
*by M***M on August 5, 2009*

We were getting dozens of telemarting calls everyday. This stops them by sending a disconnect signal to tell their computer phone dialing system your number is not there. They go on to the next one!You hook it up inline on a regular phone, or VOIP, and it makes a "signal" every time someone calls. It also makes the same "signal" when you pick up the phone. That can catch you by surprise. Sometimes, friends call and ask whaat the noise was but that is all it sounds like.I just got a call as I was reviewing this...the telemarketers call, they get the tone and hang up! No more wasted time with them. Even if you pick by accident, you still get the "signal" so if you thought it was someone else their computer will disconnect instead of putting you through to a rep b/c it heard the tone first!Very good product. Ours had a dead batttery, no big deal just went to Wal Mart.Get them before they run out! We do debt settlement and short sales and could not live without this!!! The banks just drive you nuts!! If you would like to hear what it sounds like dial 469-424-2066 and check it. If you need a short sale or debt settlement your dialing the right number anyway!Thanks!

### ⭐ TeleZapper TZ900
*by D***R on February 21, 2009*

Mine doesn't work. Followed the directions, let it run for 18 months or so, no luck. Finally changed my phone number. New number was fine for 6 months then the dunning calls for "Kevin" began again. Follow up: Ah Ha! I installed a new battery (CR2032) and now it's sending its three audible tones. So, if you buy this, buy a fresh battery too! Update: Works Great! No more dunning phone calls for people I don't know! However, to tie it all together, I've also stopped answering my phone. I just respond to voice mail. No telemarketing or dunning calls for a month now! Hooray!

### ⭐⭐⭐ The product is nice, if you ever get it.
*by G***H on November 16, 2009*

The TeleZapper works (I think) but the acquisition was a nightmare. I ordered it and received a confirming e-mail that indicated I ordered it and it was being shipped. The e-mail also had a suspected delivery date that turned out to be an absolute fabrication. I tried tracing the package and it just seemed to drop off the edge of the world. I ultimately received the device about a month later so I really can't tell you how well it works since it just recently was installed. It does not seem to work on political calls but, being political, these calls are probably being made by entities that have not called twice in the last 2 or 3 weeks and the device has not had an opportunity to scratch me from their database.
