The ZEP100 actually exceeded my expectations (how often does that happen?). I assumed I would at least have to pick up the phone and engage in conversation with the telemarketer. But luckily, I have Caller ID, and luckier yet, the ZEP-100 will work even without lifting the phone from the hook.

When an incoming call shows "UNAVAILABLE" on the Caller ID unit, I simply press the button. The phone stops ringing and the recording plays twice. And that's a key feature: Most calls are generated by a computer, which does not switch the line to a human salesperson until it hears a voice. By repeating the message twice, the ZEP100 guarantees that someone will hear the entire message, even though the first few seconds may be playing to deaf ears (the computer).

Even if you don't have Caller ID, you need not have a conversation with the caller. If you say "hello" and do not hear an immediate response, you know you've been called by a computer. At that point, simply press the button and hang up (in that order!).

My only very minor complaint is the chintzy strip of weak double-surface tape supplied with the device. It didn't stick very well to the caller-ID box. So I simply cut a larger piece from higher quality stock.

My conclusion: If you dislike telemarketer calls, the ZEP100 is a MUST-BUY device. It's inexpensive and it WORKS!


Blast the Telemarketers!   July 17, 2001

Wow, telemarketers are annoying! I can't tell you how many times I get called each day from some outfit trying to give (sell) me insurance for a low-low rate, or how many "free" vacation trips I have won! I got "caller ID" thinking it would solve the problem, but it hasn't, neither does "anonymous call rejection." So here is a device that allows you to "fight back" at the telemarketers. It plugs right into your phone then you plug the phone line into it. Once your 30 second install is complete, you sit back and wait, it won't be long! Once you get that annoying telemarketer, simply push the button and hang up. They will then hear a nice tone and then told "I'm sorry, this number doesn't accept calls ..." This is the best thing since Caller ID! I liked it so much, I now have one on all my phones!


What a Relief   October 31, 2001

I use this device almost every day. Because I work out of my own home, several different phone numbers funnel into my home. So I get a range of unwanted solicitations.
Installation was extremely easy. It worked immediately.
I still try and tell the salesperson that I am not interested, but if they don't pay atention and continue on their spiel, I hit the button and let the machine take care of it. The message from the machine tells them to take you off their calling list, and maybe even that works, because I don't get calls from stockbrokers anymore, in my experience they were the worst.
In short, its a piece of technology that makes your life easier and lowers your stress level--a rare combination in my experience.


Short and Simple review on Zenith ZEP100 EZ Hang-Up   June 12, 2006
 5 out of 5 found this review helpful

I was rummaging through old stuff at my parents home and stumbled on this item hidden in a box.
I did an internet search on it to figure out what it was and found the answer.
I decided to plug it into a phone and try it out.

Hmmm the last review was done in 2004. It's now 2006.

My take on this:
Amazingly funny, yet effective how this little device can ward off future call backs.
You can use it on wrong numbers as well. (Actually, anybody that calls you)

*If you have caller I.D, Simply press the button to activate the message. (No need to pick up the phone)

*If you don't have caller I.D and pick up the phone, stop talking press the button and hang-up. (Not as effective as you can see)

So you want to know what it says?
Beep Beep..."I'm sorry this number does not accept this type of call, please regard this as your notification to remove this number from your list."..Beep Beep..."I'm sorry this number does not accept this type of call, please regard this as your notification to remove this number from your list."

I also found the Tele-Zapper in a box and found it useless in regards to NON-Automated telemarketers. (It only works for an automated computer generated phone call) You can't press any button. Do a search for the Tele-Zapper and find out for yourself.

Overall, A great little product. I've used it for two weeks now and noticed that the usual numbers I get are no longer calling. If this somehow becomes too steep of a price to pay, go ahead answer your calls and tell them off, Check your caller I.D and decide not to answer. They will continue to call.

For an added safety measure. Register your number on the "Do Not Call" List. Do a Search.
