Am looking for a Via Ferrata set for a trip next month, and have spotted this: https://www.alpinetrek.co.uk/rock-empire-dynago-via-ferrata-set/

It's quite a lot (like, at least 50%) cheaper that most other equivalent lanyards from well-known brands that I can see - even accounting for the breaking system (sewn webbing type).

Am I missing something, is there a catch? 

Thanks in advance for any thoughts.

I don't know much about Via Ferrata but Rock Empire are a well known (in Europe) and good quality brand so you should have no concerns in terms of quality 

The main difference from the more expensive set sat next to me is that you can get the legs of that one twisted together, some of the more expensive ones have spinners fitted to prevent this. If this will be an issue is down to personal taste.

Yes a well known and respected brand, but not top end. It will meet all the relevant CE safety standards, but lack the finesse of someone like Petzl.

Good bit of kit. No catch. I mean, it will catch you if you fall. But it shouldn't: don't fall on via ferratas

Fantastic - thank you everyone, that was the sense check I needed!

Maybe they've shot up in price but I'm sure our Edelrid via ferrata sets weren't more than that a few years ago when we bought them. Are they all a lot more expensive now?

Yup. Comfortably north of three figures, for the fanciest sets these days.
