They had a promo on WHT so the 25$ package came with 4gb ram in my case.
The VPS was fast most of the times. I used it as a legal torrent seed box mainly because it had 2x 1gbps connections. I couldn't push more than 50mbytes/s, so I would say that it's connected to 1gbps or the traffic is not well load balanced between the network connections.
I saw support online on their page couple of times and they do answer if asked for something. The support tickets are answered within couple of minutes or hours depending on the time of the request.
I was impressed with their disk speed. Almost no IOWAIT when seeding huge torrents.
About the bandwidth, I used more than 10TB of data in one month, nobody complained. In the panel section is mentioned that I have 100TB total BW.
