sad
So bought these expecting sizes to be as stated. In general I've found most magnets have a slightly larger tolerance rather than smaller. For my use I needed the minimum 6mm I'd but they were actually 5.80mm so didn't suit my needs. While sizes weren't right, AMF didn't hesitate to refund me instantly hence the 4star rating. So buy with confidence but don't be disappointed if sizes vary a little.
AMF Magnetics reply: Hi Jus, thank you for your feedback! Most of our magnets have a tolerance rating of +/- 0.05mm so it's unfortunate these magnets didn't suit your application! Please don't hesitate to get in touch regarding sizing in the future.
