I bought this item as a birthday present for someone else. About three weeks later I questioned them if it was working okay. Unfortunately they were getting terrible static when using the unit. I questioned to take a look at it to see if it worked better in my vehicle but had the same problem. I tried multiple frequencies and multiple music sources with the same result.
In any case, my 30 days to return the item was up. The company did offer to replace it but I didn’t have any confidence a new one would work. I bought a different gift and this one went in the trash.

Waste of money! Never ever reckon of buying this product.
Even though it says it can do a strong Fm transmission in various FM frequencies, it works with only one frequency.
The FM transmission quality is so terrible. You get a lot of disturbance.
I had been using another FM transmitter/mp3 player for the past 3 months, i bought that for $12!!, i bought the soundfly since my ancient player did not had the folder-shift option but i made a incorrect choice. This product is worth only $2, not $34.
If you are lucky, the remote will work.

I’ve spent about five hours trying to get this unit to work through my car radio. After matching both frequencies and trying to play my SD card there appears to be no transmission to radio at all. I even re-loaded my SD card three times to properly marked “MP3″ folder. The unit lights up when plugged in…the remote control changes all functions but no sound on car radio. I cannot find manufacturer on Internet for troubleshooting. My 30 day return to Amazon has expired due to vacation so I guess this goes into the junk heap.

I have found this product to be like all the other mp-3 type car players ,just more expensive. This suffers from the same problems that plague the rest ( that I own ). The player repeats in the shuffle mode constantly when I know that theres at least 400 songs it hasn’t played. There is also no way to see the song #’s or increase to songs by hundreds as in other models. This is better made than the others but is it worth $25 more – I don’t reckon so.

I bought this device to play and charge my Sansa Clip in the car, and charge my phone through the USB port. USB and SD music wasn’t high on my priorities but its bookmark feature via the remote is one vital feature for books and long tracks that to date similar devices rarely have.
First the excellent stuff:
FM transmitter worked very well on multiple frequencies with minimal static, even in a large metro area. Certainly not CD quality but I mainly listen to books and have lots of road noise anyway. The memory feature was nice, and I found the 87.7, 87.9 frequencies to be the most clear over my commute. Given the many other terrible FM transmitters I’ve seen reviewed this one seems near the top.
Satechi did a excellent job of working with me to ensure the soundfly would meet my needs, and when I finally hit a roadblock, provided a refund upon return.
Now the terrible:
USB would not charge my Motorola phone. The power output was the low variety (5V@100mA) instead of the high level (5V@500mA) most USB phones require. Through email they confirmed the soundfly would not charge an iphone. Not a deal breaker, but it shouldn’t have been an issue.
Another glitch was that when the Clip was plugged in to charge, the USB port read the Clip as a mass storage device (like when it gets synced to a PC) which disabled the analog audio from the Clip. So I couldn’t play through the audio jack and charge at the same time. Not all the fault of the soundfly (which was trying to read the music on the Clip), but since I wanted to charge the Clip in the car was stuck.
Even though I hadn’t bought the soundfly with the USB in mind, after this I realized I could skip the audio jack and play the music through the USB port. Much cleaner and I can charge while playing music, right. Incorrect! Problem is the soundfly CAN’T PLAY MUSIC WITH DRM! I considered this a major flaw and it resulted in the product being returned.
Minor issues:
I will comment that the file system was less than intuitive. I made an MP3 folder as described in the thin manual and place some music in there (both DRM and non-DRM files). The soundfly never read that music, but instead found the other music on my Clip. Once I realized it couldn’t play DRM music I didn’t bother trying to figure out how it sorted my files. I didn’t try just a memory stick or SD card since DRM music has to be synced on my Clip. Having a large memory stick would be honestly hard to sort through.
Construction seemed a small flimy and awkward for plugging in and removing all the time, which I did since there is no power switch on the soundfly and my power plug stays on always. I left it on during the day, but didn’t want to leave it on and exposed for theives in my neighborhood. Probably would recommend an exension that could be removed to save the soundfly.
Starting the car after listening a while caused a power interuption which reset where the USB music was playing. Somewhat annoying if you ever sit in the car before getting going. No problem like this when shutting the car off.
The remote was nice but the receiver on the unit seemed very sensitive so I usually had to look down while driving to try and figure out where to point it to change the radio channel or the music playing. Much more distracting that my car radio, but mabe it would have gotten simple over time.
The Bottom Line:
If you want a excellent FM transmitter, and dont need a charger, or to play DRM music the soundfly will probably be a excellent match for you. It has some other minor issues that are balanced by some very nice features. Unfortunately it wasn’t for me. I’m going to try the griffin itrip universal plus next.
