Stephen Zander: The calculator is ready out of the box thanks to the solar powered battery - not a new tech but still better than reg batteries. Small overall which is great for your office desktop, yet it still has decent sized buttons to counteract my fat-finger issues haha.

Karen F.: I like that the numbers display is tilted up. Also numbers are large and easy to read.
There is no off button, but I use it on solar power and I did not put in a battery although there is a place for one. I keep mine in a drawer, as soon as I pull it out of the drawer it comes on.

booboo: This is one of the best calculators I ever used. The numbers are large and bright. You don't have to worry about
batteries with solar power. I keep mine in close by to figure checking accounts when I write a check or debit card.
All I can say is if you need a new calculator this should be your choice.

MIKEY: ALL THINGS CONSIDERED THIS IS A GREAT VALUE FOR THE MONEY. BUT BE WARNED THE INSTRUCTIONS PRINTED ON THE BOX ARE CONFUSING AND OBVIOUSLY MADE FOR SEVERAL OF THE COMPANY'S CALCULATOR MODELS. FOR INSTANCE DON'T GO SEARCHING FOR THE SQARE ROOT KEY, THERE ISN'T ONE. ALSO THERE IS NO EXPLANATION FOR WHY THERE IS A "GT" KEY OR AN "MU" KEY OR AN ARROW KEY. THE INSTRUCTIONS ARE INDECIPHERABLE, BUT YOU CAN FIGURE MOST OF IT OUT, AND THE PRICE IS GREAT. I'M SATISFIED SO FAR, BUT I JUST GOT IT.
