Recommendation:My star rating for reviews here on Amazon depend on the price and quality of the product for the price that was paid. It is excellent for what is. The only thing is they are constantly out of stock of certain colors and sizes. I kinda dislike the wired USB dongle, coming from Logitech G930 headset that has a transmitter like a USB flash drive. All in all this is a very reasonably priced gaming mouse that feels good, looks great, and gives you a smooth gaming and web surfing experience. Ive owned my pair for 3 years now and use them daily to walk my dog. I do not understand how this happened. I will try to request a manual and see what happens. I felt comfortable dancing the night away in this dress in a thong with no nip or butt slips. Thank goodness for amazon prime and next day delivery!
