Welcome to Geekhack!
Some people have had no problems at all with their Razer keyboards. Imagine if everyone's Razer fell apart as quickly as the ones you'd hear about - they would have been removed from the shelves years ago. In general it is the dissatisfied with the loudest voices, so I wouldn't worry too much about it.
But wait until you have tried a different mechanical keyboard, and you might find a few things you were missing on the Razer
I nearly bought a Razer, but I joined GH to ask a few questions, and ended up getting a Ducky instead. I have no idea what would have happened had I taken the chance on the Razer and not joined GH.
