Any experience with Kraken’s crypto-backed loans?

Hi everyone,
Has anyone tried Kraken’s borrowing feature, where you use your crypto assets as collateral to borrow funds and invest them yourself? I’m talking about crypto-backed loans, not the Challenge feature.
I’d love to hear your experiences. Is it worth it? What are the risks and things to watch out for?
Sorry if this has already been discussed here, I couldn’t find a recent post about it.
Thanks!
