While this thermal imager will never stand toe to toe with high end premium models, it's all most people will ever need, and more.I've had absolutely no issues with thermal accuracy.Responsiveness is nearly immediate. In fact, this imager picks up thermal variance fast than imagers I've tested that carry 3 times this one's price point.The camera isn't HD, and is low pixel, but it's clear enough to fully understand what you're seeing.Durability is very good. I've dropped this imager several times when fiddling around with my truck, and it's still working fine.Bottom line:This thermal imager is all 95% of the public will ever need.5 stars
