maybe it was lube? it was a dark orange, looked identical to ear wax, i have no experience with it so i cant tell lol
and no it wasnt his lack of clenliness haha. It was part of a payment/trade for my nexus. I actually have another tenkeyless with blues that has 3 hours of use on it, that will be sold as well. I've cycled through all the MX swtiches, and love browns/reds. Blues are nice, just so damn loud, especially when your typing/gaming past midnight lol. Browns will be my typing board, and reds my gaming board
Now i just need a clack for each one and i'll feel complete, haha
