Glad i selected this model. Higher resolution than most models in the same price range. Pass-through / vision camera has come in so handy. Rechargeable , it has light , screen is bright and clear and it is more durable than most.On the first day of a show I check all my gear with an amp clamp and the thermal camerathe rest of the show run I just use the camera every couple of hoursThe color spectrum is dependent on the min/max of what your looking at. Red could be 79* one time then 150* the next. You have to keep an eye on the numbers not just the colors Battery life is goodThe menu is easy but the manual is briefI've seen some minor freeze ups but that doesn't bother me all in all I like it and coworkers have purchased it as wellI purchased this thermal camera to spot hot/cold spots in our house which it has done perfectly. What I didn't realize was how many other uses it had. I replaced a cracked glass on a cell phone back and could 'see' how evenly the heat gun was heating the back for adhesive removal. I also do electrical/electronic work and it's amazing how sensitive the thermal sensor is. The scale on the right auto scales to only include the highest to lowest temps the screen is showing which is 'very' helpful. It autoranges automatically while the top (main temp indicator) shows the center point. The battery also lasts for a very long time. I love this thermal camera for what it is. Although it does not have a visible camera overlay for better presentation it more than makes up for it with a higher resolution thermal sensor at this price point.I love what the device allows for. I will be purchasing an additional thermal imaging camera. My next purchase will have video capabilities in addition to thermal imaging…oh and ideally, the capability to use a visible light camera on the same device.Bought this for a house inspection on a new home I was buying. The IR feature lets you see insulation gaps, electrical breaker heating (AFCI's run warm at about 105 F), hydroponic floor heating, stove pipe issues, exterior furnace temps-leaks, door and windows leaks, etc. Anything where heat or cold can be an issue. On the screen it shows you the high and low temp and locations where they occur, and avg temp on surfaces. Battery life was very good. Really good value for the money. Not sure what the rating category for "warmth" is supposed to be for.Easy to use came quicklyMine freezes up every few seconds. It starts working again after a brief pause. When it's operating, it's great. The option to have it highlight hot and cold spots is handy. I've used it for troubleshooting HVAC output, finding overheating components on circuit boards, and determining which appliances aren't cooling properly. It's been very helpful, so much so that I only remove one star for the aggravating pauses.Got this unit to see why our house in the middle of Summer in Houston Texas couldn't stay cool. Discovered we had some insulation issues and some of the windows were producing 95 degree heat during the afternoon!Allows you to take snapshots and shows the hot and low temp spots with a box that tags the area.I am not a professional that would need this tool on a day to day basis but I would say from my point of view it competes with the more known name brand.Sturdy construction - would recommend...
