Hello. My mouse got broken last night...so I was searching for a budget gaming mouse....20$ at most (very budget 😀 ) ...and while searching on ebay...hadn't tried amazon yet....I found this....http://www.ebay.com/itm/Razer-DeathAdder-PC-Game-Multi-Color-Ergonomic-Gaming-Mouse-Suppot-Synapse-/282218540493?var=&hash=item41b5892dcd:m:mKZVzg6rU0ahNIg5lbGY83A is this the real thing or not? Because I don't know what else I could buy in this budget....
