Legalys Panama immigration law firm experiences?

Hey folks, I’m planning to apply for a Friendly Nations visa and have been considering several law firms.. 4 to be precise

My experience so far is that most firms are quite slow to reply, with exception of Legalys that replies almost instantly. I checked their Google reviews and those look solid.. HOWEVER on Facebook some ppl gave really nasty feedback about the service quality…

So just wondering if anyone used that firm and what was their experience. Thanks!
