"Not worth the $15.00 i spent on it"
i bought on of this from Wal-Mart, and i wish i have just saved the money and spent it towards a better car adapter. the batteries die after about 3 or 4 hours (assuming you take them out, if you leave them in, they die overnight) and it's terrible at getting radio reception. when i drive from college to my house i change the radio station on it about 5 times in an hour and a half.

"Don't waste your money!"
I bought this with the assurnace of the salesperson that it would work well. It doesn't!! I have yet to use it in my car or home that I don't experience static and poor reception. I live in a rural area so station interferance isn't even a problem.

"Save your money"
If you live in a locale that has a multitude of radio stations that come in relatively well, this puppy doesn't work at all, it isn't powerful. You end up spending hours just trying to adjust the damn thing so it will be picked up by the radio. When you finally find the "sweet spot" in your vehicle, the sound quality is so awful (LOTS of bass distortion) it's not even worth listening to. To top it off, it eats batteries like a mofo.

"A Decent FM Transmitter"
The Belkin Tunecast is a decent performer as a no frills, small FM modulator. It is one of the better portable modulators you can get because it has a relatively high power transmitter. The FCC may cause that to change, however. Many fault this unit for not performing as they expected, but I don't find those critiques to be very valid. The unit performs fine, even in the clogged airwaves of the Los Angeles area, as long as you position it properly and have charged batteries installed in it. I have used it with my iPod and my Sirius satellite unit (which is necessary because the FCC forced Sirius to reduce the built-in FM transmitter power of new units to the point that the built-in transmitter is essentially useless).

The one big downside is that the Tunecast eats batteries for breakfast, so if you're considering purchasing it you'll want to get rechargeable AAAs. I suspect that many of the people who were unhappy with the unit's performance were using older, partially discharged batteries. I was astonished when the Tunecast seemingly ate through the battery power of newly purchased duracell rechargeable batteries in less than two hours, but when I charged them over night and tried again I got solid performance for many hours. If I had seen or known about the Tunecast II when I bought the Tunecast, I would probably have purchased it over the original version just to get the wider tuning options and the LCD. On the other hand, it's likely that the Tunecast II is even more battery intense. FM transmitters are not the greatest solution, but you can make this one work for you if you give it a chance. Do not be dissuaded by the negativity on Amazon: This is not a bad product.

"DO NOT BUY"
Does not work in the car. Works only with a fixed fm radio and very near. DON'T buy this garbage.
