Does Jupiter Jack Really Work?

JJ is an inexpensive FM radio transmitter made in China. Even with the ridiculous $8 “S&H” per unit, the price winds up being around 13 bucks each -less than an earbud, so what do you expect – a BOSE?. To the idiot woman expecting they send every possible adapter – GET A LIFE. Your phone is some kind of TracFone oddball that does not use the normal headphone jack. Go get a real cell phone. To all the other morons who are whining about “static” TURN THE UNIT ON. When the unit is switched on, it is transmitting, and the static is replaced with YOUR PHONE CALL. Imagine that. This requires reading the directions, which most of you ignoramuses are too stupid to try. The guy who said being in a city is a problem has a point… because of all the bootleg and low-wattage broadcasting going on there’s a better chance one of the freqs. they assign will have some interference. So switch to a different one.

The Jupiter Jack works in two ways:
1. very well
2. very poorly
It all depends on where you are.
If you are in a rural area or in the wide open spaces, you’re in business.
If you are in the big city, forget about it.
Jupiter Jack uses a public FM frequency.
It’s like an old time party line or a public restroom. The more, the less merry.

My wife bought this for me and I followed the instuctions and voila it works perfectly. IF you can read and follow instructions it is simple to operate the voice is crystal clear on both ends. I have been looking for something this good for a long time. I would also recommend the Magic Jack.

Tried different radio frequencies including the two that they recommended and it DOES NOT WORK!!!! Tried with an MP3 and it DOES NOT WORK!!!! STATIC works great if that is what you want!!!
Can’t wait to return it…..

If the directions are read and followed, there should be no problem. I got a lot of static on 99.3 but when I turned the switch ON on the jack, my call was vey clear -no static.

I purchased the Jupiter Jack and tried to work with it. I tuned to both channels as directed and all I heard was static. I do not recommend this product at all….

I purchased the Jupiter Jack for my phone as well as my husband’s phone. This product wasn’t compatible with either phone! I phoned the company and a representative with a “strong accent” tried to convince me to keep them. I asked her why when it doesn’t fit my phones. She said, go online and for your “Nokia” phone, you can get an adapter that will fit, “NOT SO” because it should’ve came with the correct adapters. As far as my phone, Pantech Slate, they don’t have an adapter to fit it, therefore, their commercial and online advertisements are “FALSE” this product does “NOT” work with ALL phones… I’m VERY disappointed because I can only get $19.99 back when it’s their fault for the “FALSE ADVERTISEMENT”!!! I DON’T advise anyone to purchase this product!!!!!!!!!

Dont know what is wrong with all of the other people that rated the Jupiter Jack. I have one and think that is works very well. No static, if you set it up as the directions say. You have to find the position around the radio where there is no static, and also try the other station. I hear that there are two models that have different stations that they use. So maybe you need the other model. I have called my wife while driving with the window down and traffic going by and she has said that she heard no noise. So, my opinion is that if you want an inexpensive way to have hands free, the jupiter jack IS the way to go.
