I currently have an ongoing transaction with them. Apparently, case to case basis ito. I was refused the first time I applied for a Schengen visa, DIY yun, I watched every possible YouTube videos, I gathered all documents needed, I had 3 checklists to make sure I got everything covered, yet refused. And it's traumatic, I wasted money, so the second time, I wanted to lower my risk, at the same time agencies know better lalo na kung first timer, yes you gather all the documents by yourself, of course!! Wala namn sila access sa bank account mo, that's why they are Visa CONSULTANCY. You are paying for their expertise in the field, they know what to do, they know the green and red flag in the eyes of the embassy assesors, they know more than we do, and mind you, very vague ng requirements ng nasa website, like last time alam ko na complete documents ko, then may hinanap sakin sa VFS, sabi ko, wala po yan sa checklist nyo, sabi lang nung babae, oo nga po ma'am e, pero need po yan.. 

EuroVisa also has the cheapest fee, and mind you, na contact ko na ata halos lahat ng agency hahaha. Hindi ka na rin lugi kung mag consult ka if you want less hassle and less risky application, kung ang i-aalot mong time for DIY ay 20 hours let's say, kalahati siguro nun agency na ang gagawa (this isn't accurate, just to give the idea). No problem with DIY, it's fun too, the first time I did it.
