These are the quietest keyboards that I have personally tested, and that alone makes them great for office use - these models are also very comfortable to type on, even for long periods of time - unlike other mechanical keyboards which can give you finger strain if you mash your fingertips for too long. The build quality is phenomenal and extremely sturdy, like that of a steel baseball bat.
MSI provides a great value with the GK71 VIGOR as it's cheaper than competing mechanical keyboards of similar quality. I'm awarding this our Gold Award because this is the best mechanical keyboard I've tested in a long time, and that's not something I say lightly. Of all mechanical keyboards I have tested, this is tied with ROCCAT's 121 AIMO for my favorite mechanical keyboard.
The Q0 numpad is a solid, sturdy numpad that will make a great addition to Keychron's numpad-less Q-series keyboards for those who need a numpad for work purposes. It's fairly quiet while typing on I joked that you could probably defend yourself from the Zombie apocalypse with the Q3 because of how strong and sturdy it is. Well, the Q0 wouldn't be quite as useful due to it's smaller size, but it's just as well built.
