I've used AVID microchips in the past but the needles seemed dull in my last batch. Curious as to what experiences have been or what you all recommend?

Thank you

I use the HomeAgain TempScan chip. No more rectal thermometers! This is where I buy them.

I had a batch like that at my clinic a while back. I contacted Avid. They had me send them back and sent me a new box.
