If you are going to buy a keyboard whether its for home use or office use, you must choose the right brand as it is the most important part for the computer to get into use.
Coming to Logitech MK 250, Its been more than 1.5 years I m using this device with no fault till date.
Earlier I had used I-ball brand keyboard, looks and design was pretty good but its typing sound is just irritable and noisy.and used it more than 8-9 months then it just stopped working.
So I replaced that keyboard with Logitech MK250(Keyboard+Mouse).It is the best in the market, it is so smooth to type(no noisy typing sound), easy extra buttons to control plus it is WIRELESS too! now what you need?
It is a combo product. No one can replace the quality and features of Logitech.
A great product MUST BUY.You will NEVER REGRET
