TechPowerUp posted a review on the Das Keyboard Prime 13
A quote from the article:
The Das Keyboard Prime 13 is Das Keyboard acknowledging that some people want the excellent build quality of their flagship products at a lower price point. Add on back-lighting, a USB pass-through instead of a hub, retain the Cherry MX switches and the Prime 13 offers an option worth looking into.Das Keyboard Prime 13 @ techPowerUp
