The first thing I have to say in this review is that this thermal imager is the best performing thermal imager I have ever seen in my market. The IR resolution is 220 x 160. If other brands have the same resolution then they are more expensive than $2000. I bought this because my company needed to detect thermal signatures of PCB defects. I've had a few run-ins with the Flir models my co-workers brought, but I think this job suits me. I made a bold statement that it's probably the best on the market, thanks for the very reasonable price. I introduced this product to my colleagues and friends who said it was excellent and worth my purchase. I'm also proud when I see other colleagues who have bought Flir and other thermal imaging cameras coming to me for mine. I recommend anyone who needs basic heat or life detection to get these for home or electrical inspection.
