Really very very very small. Kind of tiny.

My fault I didn't read the description but they are very small and not all durable. Not as good as the one with the stirrer. Should not be returned.

Pros
  • Great for outdoor activities
Cons
  • Not sure

Excellent value for money

This set includes a wide range of sizes, from tiny to quite large. As an experiment, I used the smallest of them in a test tube and was able to create a whirlpool. The strongest solvent I currently use is pure lab grade ethanol so I can't comment on the resistance to stronger chemicals, but so far the bars have not been noticeably attacked by solvents at this level.

Pros
  • Elegant design
Cons
  • Long delivery time

Not all wands are created equal

When the solution is heated in a beaker on the stove, one of the two large wands begins to wobble rather than rotate as the speed increases. Take out the stirrer and replace it with another one of exactly the same size from this kit and immediately put it back up to the same speed and it spins properly and I can keep increasing the speed as the solution gets hotter. If I try to leave another stick in it, it will keep tumbling instead of spinning at a certain speed no matter how hot (more…

Pros
  • Pretty packaging
Cons
  • Can't remember
