Comments on Cooleer for Android

★★★★☆ tia f · Mar 30, 2026
"ATTENTION THE APP STILL WORKS!!!!" Please, for the love of God do not throw away your user manual. Look at pg4 in your user manual, and it tells you everything you need to do to connect your devices Wi-Fi to your phone, iPad, or whatever ..... Look I couldn't figure it out for a while until I looked through the user manual. You will find the device Wi-Fi Name on page 4 as well it's SL-××××××. This will save so much time and frustration.
★★★★★ Cassandra Kunkel · Dec 23, 2023
Works great! I turned off Wi-Fi, powered on the tool, connected, and turned on the app using my Samsung tablet. It took a bit to get used to the camera - it seems to be oriented to gravity? Not sure how to explain it. But moving the tool does not move the camera. Which is actually really neat so that you get a better display without a ton of shaking. Did you know we have hairs in our ears? I don't know if I can get over that 😆
★☆☆☆☆ Lynda Stephens · Jul 9, 2022
I connected the device to Wi-Fi, but then it says that there is no device connected. Useless, I'll be returning the product.
★☆☆☆☆ Marguerite Vallespir · Dec 6, 2023
App does not work at all. Product (ear cleaner) came in with all pieces but the app does not work. The product is supposed to have its own Wi-Fi, but you cannot connect/stay connected to the app for more than 4 seconds. If you get the camera to work it stops after a second, and you can not fix it. Returning product.
