This is my honest review for my 3rd month with Sentris.
At first, when buying from them I was cautious due to some of their bad reviews. When i ordered a server they had it running in about a day, and everything was as they had promised it. Their support takes a while to respond ( a few hours in my case ), but they give detailed responses and they try to help however they can. The uptime on my server has been very good, and their network only slows down once or twice a week, which is fine for what i'm doing.
Overall, they are a good host, but if you need fast support that can get things done in an hour or less, i do not recommend them.
