Changing hosting provider back in 2010 to my old provider Heart i thought initially they were good, how wrong i could be.
Over the years my VPS server got slower and slower and finally earlier this year my VPS was lost due to Heart having problems as usual.
Finally after nearly 6 years with Heart i made the jump to Smart.
My new server has less spec, costs me significantly less per month but is a good 50% faster.
The support team reply in 30 mins to an hour comparing this to 24hrs at there worst with Heart.
Best of all no contracts. Smart are great and i do not have anything at all negative to say about them.
Personally i wish had just found them sooner and skipped the nightmare i had with Heart.
