I love the memory size as I can load many of my albums onto it without having to update it constantly. I also like the battery life as I can play it for many hours while travelling without having to recharge. One fault I do have is the number of times I must push 'buttons' to change the volume or turn the MP3 off. As volume change is something that needs to be done regularly due to variations in recordings, having to push the volume button three times when in play mode with the last having to be held before being able to adjust the volume or to turn it off is not user friendly especially when in an armband while exercising. My previous Sony had a side button with an + or - and was more user friendly. Otherwise, I am relatively happy with it and would consider purchasing again but next time with bluetooth.
