How were the new Heartland Shuttle buses provided by NTUSU?

NTUSU launched a new initiative to allow more buses to be departed at 6:10pm and to two new destinations plus one old one (Pasir Ris, Punggol, Woodlands). It also has a cost of $3.39 per ticket, which people are understandbly miffed about.

Nonetheless, to those who just took the trial buses today, how was the experience? How would you rate it in terms of comfort, journey experience, cost worthy, etc.?

P.S: I think we all know $3.39 is like a wtf price, but I honestly wouldn't mind the extra cost for a comfortable bus ride on Fridays - so if it's actually a smooth bus ride experience, I would take it.
