I myself owned a trail lrf which would not hold zero at all.
Well, I actually talked at length with several people at Sellmark and got a slightly different excuse as to why the zero was shifting, everything from a non-fixable firmware issue, breaking internally where the housing mounts, as well as a mix match of different materials. I suppose all these things or a combo of them are causing problems.
[beeep], one guy even flat out said they really don't know for sure.
I too ditched the Pulsar product but will say they never once denied the problem. I'm only one of two that I know of that actually got a refund.
I've read about problems with the Thermion on other social media sites.
Bottom line seems to be Pulsar fans are fans UNTIL the problem(s) effect their unit. Some companies/vendors defend Pulsar at all cost simply because there's big money in the thermal game.
Because of the CS I might give Pulsar/Sellmark another go some day... but not until a unit is tried and tested in the field by end users for at least a year with minimal issues, as we all know things are not perfect.
