Doing a quick google search "Logitech G710 broken caps" will bring up a long list of woes people had with broken caps.
Now, I don't think anyone imports this, so I'm planning to get one from @minitt bro, meaning no warranty (for now).
The reason I'm still interested in buying this keyboard is it's white backlit led for all keys. Every other cherry mx blue keyboard has blue backlit led which I hate, and quickfire pro has partial led lighting and it's red (not bad but white's more preferable).
Now, I'm mostly asking for opinion here. I've read that a logitech rep said keyboards from 2013 and late 2014 had this problem, meaning if his words can be trusted, 2015 keyboards should be okay. Also, if the keys do break, there are some 3rd party keycaps that are said to fit in g710+.
