The targets I ordered came in. I got a pig, a coyote, and some patches. I will try to post some pictures when my friend lets me use his thermal again, but I will say that I am impressed. For sighting in, there is probably not much benefit in them compared to a handwarmer or hot nail other than the fact that we could spot our shots from 50 yds with a 6.8. The targets reflect cold so the bullet impacts really stuck out. Nice not having to walk back and forth from target. We also shot some at 150 yds with my buddy's 35mm mark 2 Irdefense. Very cool to be able to practice your shot placement/grouping from a distance with the thermal. We have a difficult time judging distance through the thermal and putting out the targets and shooting them at distance was an eye opening experience that I think will help us next time we have a longer shot. The guy who sells these said that you can lock on to these targets with a javelin missile..... lol.
On a side note, just using the patches they sell for patching the targets was pretty cool for sighting in. They are 1 inch square and really bright through the irdefense. There was like 400 of them on the roll they sent. You have to tilt these targets back 10 degrees or more per the instructions to get them to reflect. We put them on 3/8" plywood and leaned them against a fence. I also found some toe-warmers at bass pro that have adhesive on the back that worked pretty good so those are an easy option too.
