I use them for 3 small websites without any problems for the half year. Not to say they are special but support always answers in the matter of hours and hosting seems to be stable. Their payment interface looks slightly messy but I can live with it. Conclusion: usual hosting for very small money, nothing bad for the user with usual needs.
I have been a user of Byet for over 3 years now, their former domain was ***** and not they have registered this domain ifastnet.com which seems to have been used by a different prior owner for spamming purposes back in ***** However in 2013 it is the domain of a legitimiate hosting business. People should know that domains expire and after that they can be registered by anyone else.
