IDEAL FOR CROSSWORD ADDICTS,
This review is from: Seiko ER8100 Britannica and Oxford Reference Library (Office Product)
Two buttons on the last ER8100 were sticky after only 4 months, this is the replacement. A very useful item, only requires one battery which lasts a good while even though it gets a lot of use. In poor light conditions it really requires a backlight, our previous model had one. We chose to have another ER8100 rather than our money back.
