My experience with this *Seek Compact* version of the camera put my fears to rest and I'm thrilled!In 2020 I air-sealed my attic & basement rim joists. I then discovered that exterior insulation (under the vinyl exterior) was poorly installed. I looked at 6 more houses in other communities and found the same result...i.e. look "under the hood" of your house and you're likely to find crummy workmanship that reduces your energy efficiency.I want to kill drafts and save $$ heating/cooling my house (and my kids houses). Where to focus my effort? A thermal camera would help, but I can't afford a pro camera. So for 2-3 weeks I read dozens of reviews on affordable thermal cameras. This Seek camera stood out due to the many favorable reviews. I favored the Seek over its nearest competitor because Seek has the higher pixel count. I did hesitate 'cuz of reviews reviews saying: image quality is terrible; the camera won't work unless you register; the camera steals information. But some excellent reviews addressed these issues for me, so now I'll add my experience. It may help others who'll consider this for future purchaseAPP ACCESS TO PHONE:I did NOT need to give the Seek app access to my phone. I did NOT need to register the camera. Here's what I did. I dug up my 2014 LG G3 phone (no SIM card). I charged it, connected to a guest network, snapped the camera into the phone port and I installed the Seek Thermal app. Pop-up windows appeared asking for access to camera, photos, mic. **I denied access**. To my delight, the thermal camera image nevertheless appeared and I was quickly seeing images! Yes the Seek focus knob is a little tricky. It requires patience. When you change the focus knob you need to wait 2-4 seconds for the image to update. If you're not patient the focus knob could appear to be useless. I also adjust my range further/closer to the target of interest as part of my focusing process. Well, in less than 5 minutes I was getting the hang of it and could easily recognize my thermal images. This was especially true when I switched the color palette. For me, 'amber' screen images were very clear.Here's the limitation in my strategy. Because I denied app access on my phone I couldn't save thermal images as I walked around my house. For many uses that doesn't matter. Looking for a hot, or cold or wet spot? There it is - problem identified and you never needed to grant the app phone access or register the camera. But if you're surveying areas in your house like I am (for work when Spring returns) it could be cumbersome to record/diagram/inventory all the needs. You probably already saw that I attached pictures to this review, so yes, took the next step and gave the Seek app access to storage on my old LG G3. Then I could walk around cataloging areas that need work. When I stopped using the camera I disconnect it from the phone, powered off my G3 and put them both in a drawer.CAMERA FIT:I bought the older micro USB style. It snapped into my phone and is a very rugged connection. There's no danger of the camera falling out even if I shake the phone. It would require dropping the camera or solidly smacking the phone on something to dislodge the camera. I did have to remove the hard-shell case and rubber cover from my LG phone to fit the camera, but this is a minor issue.BATTERY LIFE: I agree that the camera is a battery drain. I walked around with the camera on for ~30 minutes and my phone battery went from 98% to 62%. Your experience will differ. For sure my 5+ year old G3 phone battery is nowhere near its original 3000mAh. May be best for you to guess you'll get an hour of power before your phone will need juice.Temperature accuracy:I brought a pot of water to boil on my stove and viewed thru the Seek compact camera. The imaging spot jumped around due to the rigorous boiling, and was reporting temperatures of 207-210 degF. Or, when I image a person, the camera shows readings of 96-97 degF. These are both more than good enough for the current and expected work I plan with this camera.IMAGES (attached)One pic is my fireplace. You can see logs in the fireplace. The heart-shaped glow centered above the fireplace is a hanging wreath at room temp (bright). You can see the horizontal mantle, the candles on the mantle and even draped decoration. Lower left corner reading of 78F is the edge of a charging plug.Another picture is of my front door - poor insulation around the door perimeter. The door window showed 57F. I have clear heat-shrink plastic insulation covering this window. The thin plastic insulation might be invisible to the Seek camera and it might be reading the temperature of the inside surface of that window. The high temp reading in the lower right corner is from an adjacent heat register.3rd picture shows exterior wall next to my kitchen sink. Can you see the dish-drying rack, a coffee filter cone and a wall plug and power cord on the right? What troubles me is the dark blob that's about in the center of the pic. It's . the light/disposal switches. Even though I previously insulated that plate with 'foam pads' from a big box store and later w/Great Stuff, it's still really cold. The cold even 'flows' down the wall and chills my sink counter. The Seek compact reveals that there's ~6" x 4" section in the wall cavity that's missing insulation. The camera revealed 3 other exterior wall outlets in my kitchen with the same missing insulation defect.4th picture is a section of exterior wall. Maybe you can ID what it shows without my description and then decide for yourself if the image quality from the camera is useful.I'm very happy with the performance/price ratio. Its' working really well and I anticipate getting lots of data that will direct my work to make my house more comfortable, less costly, and more environmentally green. Thanks again to the positive detailed reviews from people before me. Good luck to those of you considering this Seek compact camera..
