Query: Good Sound Quality - Hard to use - Freezes a lot

I have this player for 5 months now & am looking already to replace it.Pros:I really liked the sound quality, FM transmitter and the battery life.Cons:1)When a expansion SD card is used the MP3 player freezes upon start-up one out of five times. It then needs to be reset with a pin (it usually happens on the train when there's no pin to be found.2)You can't navigate the music files from the Expansion slot to the Actual players memory. You have to manually set the player If you want to select from the SD card or the players memory.3)Poor instructions in manual (pdf) included.4)Hard to navigate the button & options.I never use the FM radio & Voice Recorder,
