8 Digit Silver and Black Ultra Thin Solar Power Calculator with Touch Screen Credit Card Design Portable Mini Calculator for Business School Basic Office

This product is utltrathin, but what do I think about it? Likes: - it is solar powered; as long as there is light it powers on - the construction material is plastic making it extremely lightweight - having a design on the backside is a nice touch - it is the exact size of a credit card - it fits easily into my wallet and other card carrying holders - it fits easily into clothing pockets - it may have an auto power off feature (not 100% sure) - it is very convenient for use at grocery and/or retail stores Dislikes: - the touch screen does not offer good responsiveness - you have to press not tap the touch screen to make an input - the level of responsiveness is not consistent - some issues occurred when sliding the calculator in and out of my wallet - I do not think that it will have a good life span - the solar panel may get scratched up too easily during normal use - it is not a good value

The best thing about this calculator is the fact that it's as thin as a little card and you can literally fit it into your wall. I also particularly like the fact that it's solar powered so you don't have to worry about charging it or changing the batteries or anything else as long as there's light, it works. It has a really cool little design on the back as well. I do understand that most people have a calculator in their pocket on their phone nowadays, but in times that the phone dies and you're at a store and trying to make sure that somebody's giving you the correct change, this thing could be a lifesaver. I would highly recommend this to anybody who needs a very portable and easy-to-carry calculator.
