I have tested it! It is really worth it as it is a one time payment. Only thing is that the servers are not too many which is unfortunate, but I was assured by support that they are working on adding more servers. Other than that, the mobile app works great, the chrome extention too. Haven't tried the windows app as from reading other comments windows detects it as a virus or smth. I would give it 5 Tacos if it was not the limit in connecting servers. For all else 5 tacos+ ! Supprt is awesome as well!
