Recently I’m experiencing Zebronics USB KB, its working fine for me. Actually I stroke my laptop keys as hammering on it so being in safe side I bought it. It fits for my work also if get dead then I could try other one also because of affordable cost(I bought it in Rs. 270).
One thing I observed in my Zebronics keyboard the zero’0’ key is hard in comparison of other keys, and my bad is it’s 6 months seller warranty have been finished, but no problem I’ve two keys for all numbers Yeee(of-course every keybord has). Overall good for money.
