I bought this product on july 2016. It works very well but after using of 1 year it shows problem. I message shown on computer display that usb not recognized and keyboard stop working. Then I unplugged and plugged mny times then it works. Only this is not a problem but some keys also not working like start button, left side control button rl, windows start button, one side pf enter button, caps lock button. I very dissapointed by this product
Their are lots of problem in this zebronics keyboard. I suggest every one that only brand dosent matter but the product manufactured brand also matters. So it is neccesary to check build quality of product and also read reviews of buyers. This is the worst keyboard and I bought a logitech keyboard and it works fine.
