Some keys won’t work right away – you are responsible for making this keyboard work

Do not use any beam spring keyboard in a mission-critical environment.

I can say this is the first time I've seen this in the sales description for a keyboard. Are these assembled from NOS parts?

Having dealt with this vendor in the past he uses verbiage like this to weasel out of INAD claims (eg. if something is defective he’ll just point to this and deny your return) - I wouldn’t trust him with a $400 keyboard

I’m not going to call it dumb, but I will will say… reading that bit, I don’t understand this product at all and could not be further from their target market.
