"Magnets are very weak, so the bigger ones may not hold their own weight sticking to a steel bar (handy for retrieving from solution) but you can get them out with a stronger magnet, and they stir fine!"
"Absolutely perfect. Nicely sealed, good magnetics, strong stirring connection with the magnetic stirrer mechanism."
"Excellent stir bars!"
"This is a nice selection of different sized magnetic stirrers."
"I only needed 2 of these but it was cheaper to get this set of 7...even though I will never use the smallest two, I couldn't see them functioning to stir anything much bigger than a thimble."
"Best value for money."
"Well done stir bar!"
"Great price on a nice selection of magnetic stirrers."

Reviews
"The bar certainly gets the starter going quickly but as others have noted, the center rivet makes a clinking sound that will go on for as long as you have the stir plate on."
"If I had it to do again I would get the 1" bar for my CPU fan 12w stir plate."
"Home brewers, youtube homemade stir-plates, you can make your own out of that old PC you refuse to toss out!"
"Best stir bar hands down...."
"Works very well in my 2000 ml and 4000 ml beakers and flasks."
"I had a 2" stir bar and my plate kept throwing it, decided to try a smaller stir bar and this one works perfectly."
"I bought this for use in yeast starters."
"After only making four yeast starters with this, this bar started getting thrown within seconds of turning on my stir plate."

Reviews
"I'm a DIY kinda guy and I've build a few home made stir plates from computer fans and cigar boxes. They'd through the bar, it was hard to find the correct potentiometers for the power supplies, etc. 4.Power supply is separate from the plate itself, making it easy to clean and pack away. The top surface is hard plastic and kinda slick, even with the moulded texture. I'd like a grippier, rubber surface to hold on to my often wet, glass container. I'm defiantly going to find a thin rubber sheet and glue it to the top of thee stirrer. There are only a few things I'd change if I designed it but it's totally functional and for the price compared to other commercial stirrers, you can't beat it."
"The stir bar immediately found the base and had a very decent whirlpool at only a quarter of the way on the speed control. Anything close to full power will throw the bar in plain water or a standard 1.042 starter wort, but if you are working with a highly flocculant yeast or a thicker solution, this should come in handy. I would highly recommend to any brewer out there looking to replace a DIY project for a fairly priced, quality made stir plate."
"Very compact, the magnetic stir bar feels very secure on the plate, easy to operate."
"It feels like a very sturdy unit and comes with 2 stirrers (a small rectangular rod and little larger hexagonal bar) The only issue I have is that the small stirring rod had a crack in the plastic - probably just a manufacturing error or it got damaged in shipping."
"It has plenty enough power, even with the concave bottom of the container, to deliver amazing stirring capacity in a 5 liter container!"
"I currently use a 2000ml Erlenmeyer flask and it handles that perfectly even though a good bit of the flask hangs over the edge."

"great product very happy with this item."
"This is exactly what you need, I'm surprised actually that this is not included with the hotplate - holds the temp sensor so it doesn't make contact with anything else - essential."
