Seems strong and it sits comfortably in its enclosure for smooth roll. For now, I know I was curious to find exact dimensions so I am sharing those, hope you find it useful (see pics). Mostly, I was concerned about the height when sitting on a base and its about 0.8465 inches as per the digital reading.
I will update the review when this is put in operation to comment on its actual strength and rolling ease. I think it should be good from my first test impressions.
