They were reliable enough as I had no issues at all when it came time for me to send my project off or change anything that may have been needed in order make things easier upon launch day (which thankfully was within two days).
However they did give us access so we could fix bugs before release which is always nice! Nothing really because if you are looking out there specifically then this isn't going be your go-to choice but otherwise everything seemed fine until any major problems popped up after implementation like our site crashing from too much traffic etcetera.
