The battery cover for the keyboard is a little difficult to attach back on, but other than that, the Mk235 works smoothly.

The fact that this unit replaces the 9-year old Logitech? Wireless Optical Mouse And Keyboard For Windows which was operating perfectly but which we had worn out half of the letter on keys creating a challenge to "non-touch" typists -- tells the whole story.

Would recommend

Price; Nice to use

Good key layout, I like the sunk in keys, would be nicer if the keys were backlit, for $20. bucks you cant go wrong

If you are using this for occasional usage, then this is a good purchase. If you using it for work or as a student do not get this as the keys are a bit clunky and sometimes when you press the key a little lightly it will not register a letter and you will miss words hear and there which means more time correcting your mistakes.

It's what I needed for ps4 and it works perfectly
