All Acer CD ROM Series is Value Series as for as CD ROM is
concern.
Because I have used ACER 40x, 50x and currently using 52x Model as well
as 56 X model in my office.
But I found 56x is making more noise compare to 52x model.
bothe the models I am using for 2-3 months, not giving me nay problem.
Working is smooth. It accepts All brands of CD’s i.e.
HP, kodak, Samsung, 3M etc.
Once I have faced Tray jam problem but that is because of
the CD which I was using is problematic.
I am happy with the both the models. i.e. 52x and 56x ACER
In my city service station is their so in case of problem I
will get the service.
After all every CD ROm has life of number of rotations so you
have to assume the life say 1 to 2 years only. this depends on individual
use.
