Depends on what you need a VPN for.

I don't know them but they seems to be from Estonia marketing themselves for evading censorship. Are you in a country that censor VPN? If not why do you think the tradeoff might be worth? The 2 hops should have an impact on bandwidth and latency and there is probably no port forwarding.

Using a VPN is just moving your trust from your ISP to the VPN. Why would you trust a VPN you know nothing about giving them access to all your internet traffic?
