Pros: realy usefull, work with all my USB and SD devices, easy to use.
muito útil, funciona com todos meus pendrives e SD card

Cons: the transmitter heat, not a great problem, only dont put this in your pocket while still hot.
the battery for the remote run out realy fast
o transmissor esquenta um pouco, cuidado pra ñ enfiar no bolso enquanto estiver quente
a bateria do controle acaba muito rápido, mas quem precisa de controle?

Other Thoughts: may be cheaper
the range may be longer too
podia ser um pouco mais barato

Bottomline: no more to say, sorry for bad english

Pros: Great gadget if you don't want to plug your mp3 player to the car (or you can't).
This gadget has many cons and could be improved much more but it is a very nice gadget and works perfect for his purpose (music playback).
As an audio input.
The remote is the best thing. It is full of buttons but you actually only need 4 of them (CH+, CH-, TRACK+, TRACK-).

Cons: Have to set the right frequency every time you turn on the car (if you don't use 87.0).
No playback memorization.
The LCD screen only displays the current frequency, the volume and the track number. It also shows a "P" when you press play.
If player volume is over 25 the it distort the sound. Can be easily fixed by raising your radio volume (not the mp3 player volume).
Sometimes there is noises coming into your frequency. This can be solved by touching by hand your mp3 player. This is a big cons because it can distract you from driving.
Has a FM precision of 0.5 and not 0.55 (as normal radio) so you can't select frequencies like 90.35FM.
Would be nice if it had an audio output to connect to other devices.
Doesn't work with WAV files.
I always walk out my car with the player remote in my hand.
Very bad instructions. Badly translated and short

Other Thoughts: Gonna try the version with the screen aswell!
Funny to see that everytime I turn left I have noises into the music. This doesn't happen when I turn right.

Bottomline: Music made easy.

Pros: - easy to use, without great complications.
- rapidity of access musics
- possibility of if hiding and using the command.
-fácil de usar, sem grandes complicações.
-rapidez de acesso as músicas.
-possibilidade de se esconder e usar o comando.

Cons: - some noise of deep, and increases with the car speed.
- always start in first music (without memory).
- algum ruído de fundo, e aumenta com a velocidade
- começar sempre na primeira musica (sem memória)
- não dá para mudar de pasta onde estão os ficheiros mp3, só de musica!!!

Bottomline: - the possibility to advance for the following folder instead of changing of mp3 file
- a possibilidade de avançar para a pasta seguinte em vez de mudar de ficheiro mp3

Pros: I buy it for my car because i just have an entry for cassette music. it works well and if you want you can plug and mp3 players on the USB plugs at the mp3 players.. the price is good too, dont need to spend too much dollars for a mp3 players (in quebec it cost like 30-40 $)

Cons: Very compact design
-Perfect for long road trips
-Plays back all your songs
-SD/MMC/MP3 (via USB port) Compatible

Bottomline: i buy one for my sister and it brokes when she fall it on the floor. i never have problem with mine but maybe if you take attention with your product you will not have problem.
