decent cheap stirrer set.
these work just fine, haven't had an issue yet using them with my magnetic stirrer/hot plate. didn't realize how small the smallest ones were and don't know if I'll ever find a use for them to be honest as the smallest one is about the size of a Rice Crispy.. but they come in a nice cardboard box with foam cutouts for each for storage. they also double as boiling beads, lol. cannot complain for $10 as they do what they say and I've had no issues.

Good assortment to have
Good choice for making yeast starters. I thought I only needed the largest size, but this multipack was about the same price as a single large one, and a good thing too, because it turned out the smaller sizes from this set work best with my stirplate. Highly recommended, especially if you've never used your stirplate before and don't know what size(s) you'll need.

Could I get a stick too?
These are good. Except the case barely holds the largest one in place. Other than storing these in a shelf somewhere I don’t know how else to store other than packaging. Not sure why I assumed there would be a magnetic stick that came with this. Ugh

Products Are Versatile & Easy To Use
I ordered these items because I like to enjoy good wine and better wine flavors. I found this assortment of items cost effective providing versatility when it comes to improving the taste of wine. A must for anyone that enjoys wine!

Simple set
Depending on the application, I could see a couple of the middle sizes having trouble staying centered. I actually use the smallest one in Aquarium testing test tubes and it works great. I also use the larger ones for mixing fertilizers. Its nice to have a cheap set of different sizes on hand if the need comes up.

Noisy
The circular bump in the middle of the bar is not good, comparing to some other brands. It causes unbalance and vibration from time to time and noisy.

Good set!
Good set, I mainly use the larger ones but I ran the small ones as a test and they’re pretty good too, except for the smallest one which probably has to do with the size of the magnet in my stirrer but it’s okay anyways
