I have both and I like the timer / beeper to let me know when it is "done".
The only thing I have had problems with on these is the little safety
switch on my ER2. The little plastic lip that tells it the lid is closed
didn't make contact after a while. Easy to eliminate the problem but I
would have liked something a bit more rugged. The eraser works faster than
many of the big "PRO" erasers and I can carry it to clients with me. I
found it worth every penny.
