Hello Codeforces,

Looking at the IOI regulations for keyboards and mice, the following are allowed to be brought by the contestant:

• keyboards (without wireless, calculation, and/or programmable functions),
• mouse (without wireless and/or calculation functions) and mouse pads,

It is worth buying a wired mechanical keyboard for IOI in order to get used to it?

What are your thoughts on this? For those who have already been to onsite IOIs, which keyboards did you use?
