FM transmitter user for 5 years, I used to make low-end 7euro I changed after 2 years. I decided to pay double thinking have much better but nay !! it is the vendor or the product in question it was a real disaster, and for good reason: After receiving a first product that does not even lit the I return it to the seller (at my expense of course !!) I have an answer after waiting a while and especially after being passed by Amazon for pressure, I even called to explain the seller's answer problem: "you do not know can not be use" Thank you !!. So I got a new one after 1½ months and result: it is far behind the low-end products that I used to use apart appearance stronger and better finished than the others but the operation level is a nightmare : -The Sound is really bad !! for good sound it is necessary to treble and bass has 0 thoroughly (something I did not do with the other). -Other Very unpleasant point sometimes if you remove it from lallume cigar and replace with the same SD card it recognizes it more and we have to put another remove and replace the ancient (so it remains tt time the trendy ... ) -Second More disagreeable sometimes it gets stuck on a record or a song while it is in total playing ... nice when we 8giga music ..) And finally he has cut every little jerk and he is recovering zero (when it decides to do so). Profit after two months of use (or rather daliénation) I decided to throw it in the trash and buy the latest model has 7,45e that I had It is unacceptable to pay double for a product line basis and see all these annoyances (which I never had before), as the seller I prefer not even to talk about .... A council fold on another product and save your money. Many greetings
