I do like it and as a whole it is an excellent device. The sound is god for the size ans seems clean and sound great, but it will not replace a full size pro stereo. The only down side is that the analog volume control does not change the volume smoothly but has a tendency to "jump" getting louder and softer as you raise the volume.The radio is sensitive enough that I do not have to extend the antenna to receive the local station that I normally listen to. Even though it has the capability to return to the last station you listen to it does not do that out of the box and the instructions do not make it clear that you have to use the auto search once before the radio does start on the lasten station listened to (kept going to 76 MHz before auto search done).So far it has played the MP3 files on the card and have not had any problems with them. The interface is "bare bones" which is expected from this style device and is more than adequate for its use (don't expect the same level of control as an iPod has).I like the replaceable 18650 battery (even though it is low capacity 1500 mAh it still gets good run time. I got it to replace an older one that had 500 mAh Nokia style battery that did not have a long enough run time. If I need longer run time I can always put a high capacity battery in and get it. It replaces my old one perfectly at a price in range of a new battery for my old radio.As a whole I like it and would recommend to anyone looking for one or would buy again if needed. It would deserve a full 5 stars except for the problems (not very severe but noticeable) with the volume control.I listen to FM radio regularly and bought this mainly for use in power outages. It does serve that purpose, but getting the quality of reception I had hoped for in an area with marginal signal strength proved elusive. It is possible that in areas with better signal strength it would be more satisfactory. The unit has a great rechargeable battery and memory card and connectivity options, and flashlight, but as a portable sound machine is no match for something you already own.The sound quality from the tiny speaker is amazing. Even the low frequency sounds come out loud and clear and voices sound natural. When the volume is turned up for large spaces, distortion is just not there. It will not recognize the large 64 GB cards, but a 16 GB card will hold all the music you will ever want to hear. I placed my albums into 14 separate folders, but normally the little set will play selections by a numbering system it assigns each sound file. If you pause the play (center button) and then press the forward (or reverse) button, it will advance (or go back) to the next folder and start playing from the top of that folder. If you keep pausing and advancing, you can select any folder you want to start listening to. Alternatively, if you write down the number of a selection that is at the top of the folder you want to start listening to, you can punch in that number.For such a small antenna, the FM reception is also rather amazing and the sound quality is almost unbelievable for such a tiny unit. Now I can listen to FM or my recorded music and sound in my parked car without having to worry about running down the battery (as I've done twice) and I can crank up the volume while I'm working several yards away from the little set. I am careful that I don't play the unit where others might be annoyed by my tastes in music or FM listening, because the sound really carries.You can transfer sound files and folders to the memory card through the USB cable normally used for charging, but it is many times faster if you insert the little card in a carrier and insert it into the SD slot in your computer.I really appreciate that it has a large Lion battery that does not have to be taken out to recharge. I think this is some of the best money I've spent in a long time.
