How many shoots!!

[NNN637015666042914705]

Can have a digital back used??
I'm looking in second-hand market for buying a back. 40k shots on a P+ series, can be a problem?
How many shoots can make a serious digital back in its life before a deep chek-up?
Many thanks

Hi

40k is nothing on a digital back, it is new!!
A digital back has no moving parts. As such it does not have any mechanical wear..
We see aerial solutions with millions of shots which works flawless with no specific wear or loss of performance.
