They are fun to roll around in your hands and snap together with a strong click. They seem well made and have nice strong magnets, the simple and repetitive nature is good as they are not too distracting other than the noise which is a little loud for use around others.

I really like stimagz classic, I even prefer them over series 2. They have a satisfying click that gets quieter as they're broken in (Im able to use it during college classes without much issue) and even though they are much less comfortable to use than series 2, its easy to do most patterns with one hand

I prefer the feel of the series II, but these are still fun to play with in the car! It's harder to get them into cool shapes because they slide around so much though.

I first found out about these awhile ago now, and I havent put them down, they are great and have good durability and are always working

Theses are in my hand all day and during meetings. Keeps my hands busy!
