Whether you need to make an extra starter, or you accidentally pitch the slurry with the magnet bar still inside, or just plain lose it you’ll be relieved to have an extra bar on hand. 
Two inches in length.
Note: This stir bar may not be compatible with all stir plates, depending on the alignment and distance between the internal rotating magnets. Compatible with stir plates Y700 and Y705

We have a 2 bbl system. I use the 2 inch bar for starters. It works well. We have been a Nano brewery for 4 years.

It never worked with my stir plate. Every time I turned it up the speed of the plate, the bar would fly off and stay on the side of the flask. Not what I thought it would be.

Unusable with Hanna Magentic Stir Plate
I have only ever used the Hanna Magnetic Stir plate sold by Morebeer, so I am not entirely sure if maybe it's a stir plate issue, but as others have noted, this is unusable. It spins for a few second and then gets thrown. I am guessing due to it's irregular surface. Stick with the 1 inch bar as it does not have this problem at all.

Not good
It will not stay on the stir plate unless it is a very low speed. It will not stay on my smaller stir plate at all

Works as advertised
This stir bar works just like they say it will. I'm very happy

Plate or Bar?
I have an old stir plate, but I could not get this bar to spin. Not sure which is nut functioning, but after reading the other reviews I'm thinking it's the bar.

Junk, Buy a 1
Gets thrown almost immediately no matter the stir speed. 1" bars work better every time.

had problems with throwing
I suspect the problems I had with this larger bar getting thrown were stir plate issues rather than anything wrong with this perfectly good looking bar. I did end up switching back to a smaller bar in the end though

Go with the 1
I agree with many reviewers that this 2" bar is thrown very easily. I had to be extremely careful bringing it up to speed and even then it would only work at a fairly low RPM resulting in a unimpressive vortex. I thought it was bad balancing/centering of the magnet on my home-made stir plate, but I decided to try the 1" version before re-engineering the stir plate. I'm glad I did because the 1" version works GREAT, it's nearly impossible to throw and the resultant vortex is excellent even on my last 5 liter starter (in 5L flask).
