Razer needs more longevity

Hey I bought two items keyboard and mouse:
Razer Blackwidow Lite - keyboard
Razer Viper - mouse

The problem is that keyboard is very high maintenance. Maybe it's my mistake. With everything open and this "barebone" design everything gets inside keyboard very easily! It is collecting a lot of dust particles and very don't like being even slightly spilled something on it. So you have to expect to disasemble this keyboard every two months and thoroughly clean it (at least 1 hour of work).
Razer Viper same thing. I couldn't remove buttons because that would void warranty, but something did get into mouse button and I have suffered for a month until the thing was gone.

I like how the products work but longevity is very low and a lot of cleaning and maintenance. I think I am going to switch to logitech when these items die. Logitech are so much more care free products and at a sane price. So thanks for keyboard and mouse, just I am not going to buy a new keyboard and new mouse every year. Razer is like a Formula1. Formula1 tires. It's very fun... for a few months and then you need either to replace it or to disasemble and clean it. With keyboard you can remove keycaps and that's ok but with mouse you can't dissasemble anything without voiding warranty.
