I wouldn't go so far as to say that "unlimited=unreliable", but their rates essentially come out to an average of $0.013 per day for hosting. That's not a lot of money to invest in hardware, support or anything like that.
When a company says that they're in their 25th year, generally that doesn't imply their company start date but rather their time in the industry. Essentially, using the marking of 25th year, they're tricking a lot of people into thinking they've been in hosting for 25 years. Very misleading. Using their philosophy I could say I have 37 years experience - since I'm 37 years old
With those low rates I'd be very cautious. Also, a 10 day testing period is not something to rave about or suggest others move over to them. If you had 6 months experience with them, that's a good window to offer a review.
Personally I'm not impressed by these rates.
