I bought batch 1 tokens the day of the ICO.  I received my tokens ON launch day and immediately set them up to "rent."  For the first few days, I would get an email every hour saying that my tokens were not rented and I needed to lower my rental fee.  I was already at the lowest fee selection.  I emailed the tech support folks and got a reply within a few hours that they "Knew about the problem."  Not long after the email exchange, the "canned error" emails stopped.  I logged in and all my tokens are rented and earning me income.  I chalk it up to just working out a few kinks. 

Knowing that I had Batch 1 tokens I would say it was pretty smooth with just the one bump.
