Problems Pulsar Thermion XP50

Hi everyone,
I'm Italian hunter, I bought a Pulsar Thermion XP50, and the first time I shot to calibrate it, some broken pixels came out, I did the procedure to for defective pixels repairs, but it didn't work.
I wrote to Pulsar that he replaced the scope, I have calibrated second Thermion and had the same problem as the first, very honestly Pulsar gave me my money back.
I would like to buy another one but without defects, but I'm afraid that even the third one is going not to be good.
Looking on "You Tube", I didn't see any Thermion that have defective pixels, even a few.
Has anyone ever had pixels that do not go away with the repair procedure?
I saw a thread from Jason, answering a similar problem but couldn't find anything else.
Maybe a wrong production series?
Thanks for your time and sorry if my english is not perfect.
Guido

Ciao Guido

What caliber rifle are you shooting?

Hi Charlie,
308 Win, DPMS Panter LR308

There’s one issue set aside, you’re not over-calibered.

Charlie

I think too, it seems strange to me that it happened on two Thermions, so I'd like to know if it happened to others

Did they issue you a new unit before you sent the old one back?

I've seen instances where a customer sends in a defective unit and that same exact unit is sent back to them.

They had two different serial numbers and I checked the second one before going to the shooting range to calibrate it, it was flawless.
