We bought two, the reviews and YouTube reviews were so consistently great.
We got them together a few days ago, and my guess is that whoever assembled one was having a bad day.
It was almost impossible to fold and open; we found that the two spring loaded bolts were way to tight.
Unfortunately, the battery falls out all the time; we couldn't figure that one out so sent a message to their Customer Service three days ago. No response. I guess she was right, we should return it for poor customer service and who knows what else was probably purposely screwed up.
