I'll preface this by saying I understand I'm very much an edge case.That said, I sleep best in a completely dark room. I have both blackout shades and blackout curtains on my windows. I long for the days when manufacturers didn't put blindingly bright LEDs on every device with the enthusiasm of a middle schooler bedazzling their shoes at a slumber party.I *specifically* looked to see if the screen of the Kaiterra Laser Egg could be turned off. I wasn't satisfied with the listing here saying it has a "sleep mode," I've been burned by other companies before.I went to the Kaiterra Laser Egg product support page where it distinctly says "Turn off the LCD display when dark."I know it's showing the stars, moon, and cloud LCD OFF screen, but I naively figured that was just the menu page for the feature since people might get confused if they were cycling through the screens and it suddenly went blank.Nope.That is the LCD being "off." Needless to say, the fine folks at Kaiterra and I have a profound disagreement as to the meaning of that word.So, I will be returning the device as it is unusable for me, absent a firmware update which would enable the device to actually turn off the screen when requested.Other things of note:The app is really poorly designed.When you set up the app the first time you must go through this whole rigamarole of pairing with the device, entering your Wi-Fi password, etc. Annoying to be sure but par for the course. Typically though, with other "smart" devices, once the device is on your network any other phone with the app can connect to it. You may need to scan a QR code or something, but it's typically pretty easy and straightforward after the initial setup.Not with the Kaiterra Laser Egg. Nope, you must go through the whole setup process again, telling it again which Wi-Fi access point to use, giving it the password, etc. Which is annoying to say the least. But hey, it's on me for having a 24 digit random password for my Wi-Fi since I naively thought "how many times am I going to have to enter this one everything is set up?" Well, at least the number of Kaiterra devices I want to put in my home multiplied by the number of devices I want to put the app on. That wouldn't be a deal breaker in and of itself, but it's worth noting they didn't put much effort into streamlining the onboarding process.Okay, lightning round!I've only had the device a day nor do I have anything with which to compare so I can't speak to its accuracy.It's relatively expensive at ~$200.It looks nice enough if you like egg-shaped things. Though it would be nice if they had color options for the ring, gold is rather gaudy in my opinion.It uses a micro USB adapter, which is fine, but for $200 it would be nice if they made the leap to USB-C. The device itself doesn't need USB-C, I'd just love to be able to get rid of my micro cords one and for all. (Ahem... looking at you Kindle!)It does have a battery, and a fairly large one at that. This confuses me since I would assume most people would keep this more or less in one place, but perhaps I'm wrong and simply lack imagination. Anyway, it's nice to have and you can move it without it turning off and needing to boot back up and reconnect to Wi-Fi, etc.The screen is a 2.6 inch LCD, it's 2021, I can find a 2.8 inch AMOLED display on Alibaba for $25. Maybe it's time to refresh the product?There's no mode which cycles through the displays, you have to manually click the menu button to cycle through. I anticipate this means most people will simply view the readings on their phone assuming they can get the app to work. Maybe make a discreet box without a screen at all?The device really is egg shaped which, again, if your like that sort of thing is nice. To stabilize it on a table though they gave it the tiniest little bumps for legs. This works well enough if you just let it sit there, but if you intend to change the screen displayed you'd best make sure you press directly down on the button. If you come in at even the faintest of imperceptible angles you'll probably knock it over.All in all, if the device actually does what it claims, you like the look of the design, you don't plan on changing the information it displays, you're not actively trying to rid your Life of micro USB cables, you only plan on having the app on a single device or you don't mind inputting your Wi-Fi password for every device you add, and you don't need the screen to be able to be turned off, then I wouldn't recommend against purchasing the Kaiterra Laser Egg.Otherwise, I'm looking elsewhere and I would suggest you do as well.
