There are times when a simple calculator is all you need, but what do you use if your phone, tablet or computer is not close at hand? In these instances, the Mr. Pen- Calculator comes to the rescue and helps complete those arithmetic problems no matter where life takes us.
The Mr. Pen-Calculator offers users two display modes: digital and LCD in case of power outages or radiation exposure during an emergency situation. It also has 4 different colors for each button that makes it easy to keep track of which buttons perform what functions using just one glance instead of having to constantly check on screen menus every time we want a specific number answered by this multifunction calculator
Features of Mr. Pen- Calculator
Reviews & Ratings of Mr. Pen- Calculator
Our Rating: 4.1 Out of 5 Stars
The Mr. Pen- Calculator is a very well reviewed and popular basic calculator for children or people who do not use a calculator often. Customers have given it 4.1 stars out of 5 on average, with many saying that they would recommend it to their friends and family members as the perfect tool for kids in school
I found 21 customer reviews at the time of writing this article, all being positive overall but some niggling points raised by one user: “This is really strange! When I push down button 1 then 2 then 3 … nothing happens”
However, no other customers seem to be experiencing these difficulties so perhaps this isn’t an issue with the device itself but just how you are using it? Other comments were much more favourable such as “Very useful product – I highly recommend buying from Michael’s” and finally “Best investment ever!”
The Mr. Pen Calculator is a basic calculator with few features, but it does not come with a stand and the battery life is poor for its price point.
