Pros
Easy to start working as a translator. You may have many project to translate. Pay on time. You take experience if you don't have enough.
Cons
Low payments for high expectations. You don't have a contract. I made more than 5 translation for more than 4000 words each article without having a contract. When I asked for it they said that will send me the contract. After some weeks with no answer they said that the project stopped because of many mistakes on their articles. Then, they said that my translation has problems and a professional translator rate me with 6/10 (I am Greek native speaker and I translated from English to Greek articles so I don't think that I made mistakes) and they continued with more experienced translators. Although, they already knew that I was not experienced translator. The payment was too low and also the pressure to be on time. If they want professional translators they have to pay more than 0,15 per word!!!
