I am using this mouse for lst 5 months, I bought it for 300 rupees, but first month it works better, after that battery becomes worst, fast draining, not working properly, totally waste of my money, it just worked for 1 month, outlooks r better but performence was very bad, I dont recommend this product, even though better products brands r there outside than this one, simply waste of money on this one, buttons r not working properly cheap quality buit.
