Minerstat is really easy to use (configuring the actual miner can be complicated though). I switched from using the desktop version to the minerstat OS and it has worked flawlessly after properly configured. Any instability I had in windows is just gone as well, and getting more hashrate and efficiency out of my system now.

Great software and service for peace of mind. A broad offering covering all your needs.
Courteous and knowledgable help when you need it and a friendly user community that pitches in.
Easy setup for beginners and flexible for more advanced users.

I love the sleek feel to the web UI, compared to other mining platforms. I also very much enjoy that i can have all of my windows rigs in the same view my linux rigs. Price is great too!
