I have been running PC arcades (internet cafes) for the last 15 years now. And last year we changed all our keyboards, mice and headsets to Razer. And the build quality and warranty for these have been the worst I have ever experienced . It has been just over a year now and all the headphones and nearly all the mice have had to be replaced, as they have all physically broken. The keyboards are the only thing that seems to be kinda still be ok. Razer Australia refuses to replace broken items but when that is what the main problem what is the use? Yes we are a public server and items get abused a bit more, but less than a year?! months in many cases. Like i said its the worse products and service i've ever experienced. Take it from my 20+ years of gaming and 15 years of pro gaming. For the price look else where, anywhere but Razer.
