I have owned two different Telezappers and have been pleased with them. The larger model uses an electric cord. The smaller, slender model (the picture will fool you, it's really small...) uses a CR2030 battery. Also, the larger model (the one with the cord) emits only the first tone of the SIT. The smaller model (the one with the battery) gives you a choice of either the first tone of the SIT or the entire 3 note sequence, which is more effective. I previously used both models on a Panasonic Phone/Fax/Copier model KX-FPC95. This phone set had a cordless phone integrated on a fax/copier. No problems, worked great. I recently purchased a Panasonic Phone/Fax/Copier model KX-FG6550 and the Telezapper does not work with this phone set. The telezapper "tone" is delayed to the point where it is ineffective. This phone set has a "base unit" with copy and fax, and the phone is a separate unit, plugged into an electrical outlet, operating on a "wireless" from the base. If you purchase phones of different brands, but similar to this type unit, it may not work well with the Telezapper. I think it has to do with the cordless phone not being integrated with the base unit. I tried to email Royal Appliances about this, but when I used their web site, I got "page not found."
A year or two ago we decided our Telezapper ( which had served us well) was dead and threw it away, planning to repalce it. When I couldn't find one at Radio Shack, I kind of forgot about it. We have been bothered lately by a lot of telemarketers so I resumed shopping. Looking at the info on your site makes me believe they are no longer effective. The most recent comment was posted in 2003! Anyone have any newer information? There is no point in spending even a small amount of money and taking up space on my desk for something that no longer has a purpose.
Do not buy the TeleZapper. It has essentially been rendered obsolete. This is from an article on Yahoo! News that came out 2/26/03:
New Telemarketing Tool Trumps TeleZapper
NEW YORK - A telemarketing tool that penetrates home privacy defenses is upping the ante in a technology battle between sales callers and consumers seeking shelter from unsolicited calls.
Castel Inc., a maker of automated dialing technology, boasts that its DirectQuest software is immune to the TeleZapper, a ... gadget designed to thwart sales calls by faking the tones of a disconnected number.
Beverly, Mass.-based Castel has been mailing brochures to telemarketers and other prospective customers touting the software, which also includes a feature that lets salesmen transmit any phone number or text message to residents' caller ID displays.
That second component allows DirectQuest to dodge such phone company privacy services as SBC's Privacy Manager and Sprint's Privacy ID, both of which reject calls that don't provide caller ID information.
Castel's software is built for the high-volume "predictive dialers" that use multiple lines to phone residential numbers and connect salesmen to people who answer.
"It's a privacy arms race," said Robert Bulmash of the privacy group Private Citizen, based in Naperville, Ill. "The industry is crowing that 'We don't want to call people that don't want to be called,' and at the same time it's calling them."
Consumer privacy devices will increasingly lose effectiveness as telemarketing firms switch to the new dialing technology - which costs roughly $2,700 per calling operator, said Bulmash.
Royal Electronics Inc., which manufactures the TeleZapper, says millions of them have been sold. The device is designed to trick predictive dialers into dropping the call by playing the three shrill tones of a disconnected number.
The privacy services sold by phone companies target another weakness of the predictive dialer - their inability to transmit caller ID.
Castel chief executive Geoff Burr labels as "unsophisticated" dialers that succumb to privacy devices. "Serious professional operations don't use that equipment - or they won't be for long," he said.
Burr said DirectQuest is not aimed at bothering consumers, but the opposite - making sales calls less intrusive. By providing the identity of the company on behalf of which the telemarketer is calling, DirectQuest gives people the option not to take the call.
The software also helps elemarketers mind federal guidelines that require accurate and descriptive caller IDs, said Burr.
"If you're an operator that calls on behalf of MasterCard, you're supposed to put out 'MasterCard' and a number that gets to MasterCard," he said.
Instead of listening for sounds that identify the status of a phone line, DirectQuest learns the line's condition by reading signals from phone company computers, said Walter Elicker, Castel's marketing director.
Elicker said privacy gadgets don't just thwart telemarketers but also bill collectors who use predictive dialers. "Collections people want to make damn certain they're not fooled by these kinds of devices," he said.
A more effective means of blocking sales calls lies with the emerging federal Do Not Call list as well as similar lists kept by some two dozen U.S. states, Burr said.
The Federal Trade Commission has said its Do Not Call list will begin collecting names this summer and be in operation by the fall. Telemarketers who phone listed numbers can be fined up to $11,000 for each violation.
Effectiveness of Do Not Call lists, at least for now, is a pipe dream, Bulmash said. The FTC doesn't regulate telemarketing-heavy industries like long-distance phone companies, banks, airlines and insurance companies.
State lists, too, often make exemptions for funeral homes and car dealers. No agency can prevent phone calls by political campaigns, charities and surveyors.
Predictive dialers fueled huge growth in the telemarketing.
A Federal Communications Commission (news - web sites) memo says telemarketers attempt 104 million calls a day to U.S. businesses and consumers. Sales revenue rose from about $435 billion in 1990 to around $660 billion in 2001.
Telemarketing advocates fear Do Not Call lists could devastate those revenues and the jobs that depend on them.
An article in the February issue of Customer Inter@ction Solutions, a telemarketing industry magazine, said FTC restrictions could eliminate three million jobs.
The article estimated that the top 75 U.S. telemarketing firms paid for 13.2 billion minutes of long-distance phone service last year. At 4 cents a minute, that amounts to $528 million in telecommunications revenue.

We've had the Zapper for many months. Before it was installed we got several calls a day/evening. The number of calls is down dramatically. Now, the phone will ring and when you pick it up all you hear is the line going dead and a dial tone. Hot damn - zapped another one! It's such a good feeling. But, it won't stop direct dial solicitors, and the beep can be disconcerting to those unfamiliar with the device. Still, we are ever so pleased to have made the investment. The dividends are reaped every night.
This model helped cut down on marketing calls quite a bit, but I still get at least one per night. The new model is a lot better, but I'm not going to buy that one. The state where I live, MN, just got a do not call list, which I think will work better than the Telezapper, old or new.
