After reading all the complaints about the new Lee auto primer called the ergo I contacted Lee and asked them about new lids so I can have spare.
I talked to their manufacturing manager (don’t know how I got hold of him) but they he acknowledged the problem people are having with the lid and said that they have made the lid out of a different plastic material and the problem has gone away. And if you have a cracked one and send it to them they will replace it free.
Very nice people at Lee.
I will let you know when it shows up this week.
