Great little desktop calculator for simple tasks.
This is a great little desktop calculator that doesn't occupy a lot of space It's easy to use for basic math like bookkeeping, checkbook balancing, computing areas or rectangular areas, etc. I would highly recommend this to others as an inexpensive small-space calculator that is easy to use, including easy to read numbers, auto-off (no switch to remember to turn off), but has a few bonus options like memory addition and recall, plus the dual-power feature saves battery life.

Pretty good but buttons feel cheap
This was a pretty solid purchase. The buttons are actually easier to see in person, which is what I was worried about as some of them are white text on light pink. The only issue I have is that the buttons seem a bit loose and require you to put some pressure on them to input numbers. This really isn’t a big deal but if you need to do fast calculations at work it kind of does wear down on you. If you are looking for a casual calculator and aren’t punching numbers all day I would recommend this. However, I probably will be getting a bit more practical calculator soon.

I Have had this for 2.5 years not and the buttons are just not very responsive. You have to hit the buttons quite hard
