Seriously. If you're buying this to be able to use with a connected app over WiFi, you're going to hate it. Most features are accessible without using an app. From what I can tell there's just a timer that can turn the unit off after a set time that is locked to the app. Otherwise, you can adjust the LED color, brightness, and fan speed directly on the unit itself. That all being said, if you want a quick review of the app, it's hot garbage. If you want help connecting, I'll include a bit at the end on how I got it working. =========================== Review =========================== This is actually a nice little bit of kit. It's compact, holds a good bit of water in the tank for at least 8 hours of use, and the fan is reasonably strong, so it pushes the air pretty far away. The best thing about it is how little power draw there is, and the fact that it's using a USB type-C plug, so I don't need to bring a bunch of cables with me if I feel like traveling with it. If I want to go camping, I can plug it up to a portable battery for my phone using my phone cable, and that's that. The filter it uses is pretty beefy, but it doesn't seem to really restrict the air flow at all. They're pretty expensive for replacements, though, and the unit will try to get you to replace them way too often for my use. You can remove the magnet in there to get some extra time out of a filter when the unit begins nagging you about it. You can inspect your filter before doing so to determine if it actually needs to be changed or not. If you're using purified (good) or distilled (best) water, you're going to likely be going through filters at a super slow rate compared to the time frame they suggest by default. If you're using regular tap water, then your filter might get pretty gunked up after a few months of use. It has a built in RGB LED light on the water tank. It's pretty nice as a mood thing or just a nightlight. It can get pretty dim, and maybe moderately bright. If you're using it for a kid as a night light, it would probably work pretty well for that purpose. I leave mine on just because I like it. The fan speeds are pretty varied. It can go from a very slight breeze to reasonably strong for a small fan. It's not going to move more air than a regular desk fan, but it does push a surprising amount of air on full tilt. With the water tank filled, it can drop the temperature in the immediate area by about 5 degrees Celcius or so. (that's about 10F) If you're using it in an office setting with an ambient temperature of 23C (73F), then you can expect to feel a nice breeze over you of about 18C (65F) or so. You can even adjust the air to blow up or down with a manual level on the side of the unit. This will definitely not cool a whole room of a house. It's pretty much meant to cool a small space of about 1.5m (5ft) cubed or so. You can expect the majority of your temperature drop to occur in the immediate vicinity of the Eva unit. You might see some temperature decreases further away, but it's a pretty steep drop of in temperature reductions the further you move out of this thing's bubble. =========================== Conclusion =========================== Like I mentioned before, the best thing about this unit is the power draw. On full blast with the fan and full brightness, the unit seems to max out drawing about 5v over 1.5A, for a total of 7.5W of juice. That happens over a standard USB type-C connector too, which is super helpful in making the unit portable. You should be able to easily power this thing over a regular USB port on your computer, or even directly from some modern phones with a type-c to type-c cable. I wouldn't recommend this to anyone who doesn't have my use case. I like being able to take this around with me and only have to have a single power cord. I don't have to worry about whether I have the correct power cable for it, nor do I need to know if my power source will have enough output for it, since it draws so little. I use distilled or purified water in it, so I don't need to replace my filter very often. For way less cost, you could get a different model in another brand that would serve your needs way better than this one unless your needs are similar to mine. For the cost, I definitely can't recommend this product. At this price point, I'd at least expect an actually functional app. And the filter replacements are way overpriced for what they are. There's a very narrow use case for this product where it makes sense. If you don't fall into that, then DO NOT BUY THIS PRODUCT. You're going to be disappointed and frustrated with it, and regretting your purchase. I've knocked off one star for the high cost to feature ratio, another star for the awful app, and a third for the ridiculous cost of the replacement filters. I would have rated the filters separately, but the unit tries to force you to replace the filters way too often, since it seems to be time based, instead of actual usage based, which is a flaw in the unit, not in the filters themselves. =========================== App =========================== If you really, really, really hate yourself, then here's how I got mine to finally connect to the app. I'm warning you, this may not work on the first try for you, and you may end up having to factory reset the Eva unit as well as clear the app data on your phone to the Eva app. It's a really horribly designed app that barely works. It's not a feature; it's a hindrance. It's an app for technophilic masochists. The way that I've managed to get it set up is to download the app first. After that, power on the EvaPolar unit. Once it's powered on, do a factory reset on it. To do this, you might need two hands. You place one finger above the display image, and one finger below. This is where you see the up and down arrows when you're adjusting the fan speed or brightness. When those fingers are in place, you press the power button. It'll show some icon on the display. Hit the fan button at that point, and it'll reset itself. Give it a minute, then power it back on by holding down the power button until the screen says WiFi. Open the Eva app on your phone. Make sure you're connected to your normal WiFi network that you plan to connect the Eva to also. Hit the plus button in the bottom right. It's going to ask you about connecting to the Eva unit's Wifi. Just hit continue until it connects you to the EvaSmart WiFi network. You should now get taken to the screen where it asks you to connect the Eva unit to a WiFi network. Tap on your network, and then enter your password. Here's the important part. You need to listen to your Eva unit. if you hear it vibrate twice, then it has connected itself to your WiFi. As soon as you hear that double vibrate, you need to manually switch back to your normal network as fast as you can. Go back to the Eva app. If you have an older phone, and it reloads the Eva app, you're screwed here. If you go back to the app where it's still at the spinning circle, just leave your phone alone for a few minutes while it's trying to find the Eva unit on your network. Do not do anything else with the app until your Eva unit vibrates one time after this point. That is your indication that the app has registered the unit to your account. At that point, the app is still probably stuck, so force close it and reopen it. The Eva unit should now be in your account.
