I bought my board last October and I have relied on my WowGo 2S to get me around campus ever since. I've driven it daily around my city for about 4 months now, about 250 miles in total. I have put my board through the wringer. Even through light rain and wet streets, some patches of dirt, and the horribly cracked and pothole filled asphalt around my university, my board has taken it like a champ. I'm a big guy, 6' 2" 220 lbs, and the board has handled like a dream regardless. Truly a great starter board, I can't imagine getting anything else. Also, super easy to work on and repair as regular wear through the normal wear and tear.
Some things I've experienced:
The neoprene seals aren't very waterproof. After a particularly wet ride I cracked open the case and some moisture had penetrated. I bought some thicker neoprene online, chopped out some new seals, replaced the old ones, and haven't had a moisture problem since.
One of my rear wheels has experienced greater wear than the other, I'm not sure if it was a fluke in the PU compound during manufacturing but I'll be replacing the wheel with the new sleeve version hubs soon anyways.
Overall I'm super happy with this board and Id happily buy again.
