## Questions & Answers

**Q: I ordered this keyboard and mouse and the keys were foreign/incorrect for about 6 of them.  Anyone else have this situation?**
A: The picture on the outside of the box I received reflected a US keyboard, but inside the box, I found a European keyboard. I ordered 6 and needed to return them all. They were not compatible with my users fingers. The US keyboard  has a wide "SHIFT" keys on both ends of the keyboard. The keyboards I received have narrow left-shift keys and various other punctuation keys in the wrong locations. The one clue is that there is no English on the outside of the box even though the photograph is of a US keyboard.

**Q: What type of batteries does it take? It says 4 nonstandard batteries. What are nonstandard batteries!!!**
A: I know this is an old question but Amazon ships globally.  Maybe the people with issues live in a country with different disposable battery standards?  In Canada, the US, Mexico, and most of Europe these take standard sized batteries -- 2 AAAs for the keyboard and one AA for the mouse.  I can't speak to the Warsaw Pact countries, Cuba, Africa or South American battery standards, I know the Warsaw Pact countries pretty much made up their own alternative standards for everything so I wouldn't attempt to use one of these there without further research there without buying a large box of AAA and AA batteries from here to use with it.  I have the keyboard without the mouse, it definitely takes two AAA batteries of which are so standard that I probably have 50 or so new, in the package AAAs in my battery box at any one time.

**Q: CAP indicator light?**
A: No, it does not have a Caps Lock indicator light.  I just purchased April 2023.

**Q: Can this be used with windows 10?**
A: Yes, I am using it with Windows 10 and have not had any problems with it.

### ⭐⭐⭐⭐⭐ Fantastic product
*by R***. on 6 April 2019*

Mouse is little heavy but the keyboard is fantastic I am using this mouse and keyboard last 7years and this keyboard work pretty good

### ⭐⭐⭐⭐ Keyboard is GREAT. I am unsure about mouse
*by M***T on 26 November 2018*

I type and click REALLY HARD (on my keyboards and mice) for my work and PC time. I have been using it for about a month now, so this product review is not based on long term use. I am writing this review specifically only for the keyboard. The keys are very VERY well designed. I saw how the keys are placed on the keyboard and I can tell that the design is very intelligent. The design is made to literally receive keystrokes at good angles from your fingers. I am saying that the the 3 rows of the alphabet have been very intelligently designed. Also, about the intelligent design, the caps lock key has a special shape which you can identify without need of looking. I think this keyboard will almost automatically make you type faster, lol. Mouse scroller spoilt soon after purchase.
