Summary: I will be giving calculators away for Christmas because i bought a few to many and i was in need for a different thing as far as counting like the wristband,live and learn,good prices so nothing is lost.
Summary: It's the most sensible calculator out there-size (perfect anywhere), use-ability, price, design and durability. Battery seems to be replaceable but at this price range, it makes sense to by a new, clean one after years of use. I hope this model is never discontinued nor redesigned.
Summary: It takes awhile to get used to pressing the keys so that they work. If you forget to turn off the calculator, it turns off automatically after 8 minutes. If you would like to replace the battery when it no longer works find the small screw with the battery cover and replace it with an LR1130 battery. I wasn't sure whether to give this calculator 3 stars or 4 stars so I played it safe and gave it 3 stars.
