Input:
I recently bought this player and have tested it with almost all kinds of CDs/DVDs/MP3s and even simply written dics with MPEGs. It plays everything and does not get soo much hot in 2-3 hrs. I played it continuously for about 7 hours the very first day I got it, just to verify the reviews I read it. Its quality is good and it has all the functions one can think of.

It would have been great had it been portable with batteries.

Options:
A: very positive
B: positive
C: neutral
D: negative
E: very negative
Answer: B: positive
