Havit gaming mices are not the top of the line components, however for the price they are really good and you can't go wrong. All of their mice are under $25 and have a DPI button. Look up these models on Amazon. HAVIT HV-MS672, HV-MS745 and HAVIT 2.4G. I have the HV-MS691 for well over a year and its been a really good mouse for the money ($18.99).
