Recommendations for a good travel keyboard?

I like to carry a keyboard around with my laptop - especially since it's a convertible, so when on a desk, it's easy to just flip the screen and use it with a keyboard and mouse.

Subjective preferences (optional, to keep the discussion generally useful): I like tenkeyless size for compactness, I use UK layout (large Enter) and a wireless/bluetooth option would be nice.

I had the Corsair K63 until now, which is great, but the keys fall out very easily (like, without force, even in bag) which makes it fragile to carry around - especially with its weight.
