I uninstalled the app and reinstalled it multiple times. Even tried it on a different phone. And no matter what it says “no internet connection” on the wifi ### 3/5 — Blurry *2023-12-31, version 1.7* I loved my scope. I’ve had it about a year but now it is so blurry I can’t see anything. Does it give out after awhile? I need this to work. ### 4/5 — 耳の中がはっきり見えて便利 *2023-09-30* 耳垢をとる分には十分な機能があると思います。 ### 3/5 — Does not work on newer iOS versions *2023-08-03, version 1.7* I have 16.5—phone cannot find MZ network Amazon reviews suggest failures starting with iOS 14 Fortunately I also have a Droid—it works on that ### 1/5 — App Stopped working *2023-08-01, version 1.7* App no longer connects to device. Huge scam ### 1/5 — Wifi Connectivity *2023-07-19, version 1.7* Wifi keeps disconnecting. Says unsecured network and it disconnects. It used to connect flawlessly and worked perfectly. Even after deleting and then reinstalling the app, I continue having the same issue with wifi connectivity ### 4/5 — MZ Scope *2022-12-22, version 1.5* Make sure to disable VPN before use. Then connect to Wi-Fi. ### 1/5 — Wireless Otoscope *2022-11-14, version 1.2* The app does not work. This means the camera tool is completely useless. ### 2/5 — ぼやけるようになった *2022-11-13* 10回ほど正常に使用できた。 長く使うと本体に発熱がある。 突然カメラがぼやけるようになり、アプリをアンインストールしてもiPadの電源を切って入れ直しても治らない。悲しい ### 4/5 — 怖い。 *2022-09-03* BluetoothじゃなくてWi-Fi接続なのでしっかり説明書を読んでから使ったほうがいいです、説明書読まずに使い始める同志諸君。 とても使いやすく便利ですが、己の鼓膜が見えて怖くなってやめました。 でも見えない部分が見えて「あ、そんなに散らかってなかったんだな…」と不安が取り除けたので大満足です。 ### 1/5 — Awful *2022-08-22, version 1.2* Unable to use, will not work on iPhone and no updates or any help at all. ### 1/5 — 使えない！ *2022-07-01* Wi-Fi接続しない ### 4/5 — Video fix for iPhone *2022-03-27, version 1.2* Thank you KILOJYLE. For your review! This is exactly what happened to me & I uninstalled the app out of frustration! It is 1 of the best tools / gift i have ever gotten! It’s helped so much & if i hadn’t read your review I was about to just Chuck it & give up out of my frustration!!!! So I thank you again for the tip! ### 1/5 — Worked for first day *2022-03-23, version 1.2* Used it the first night I received it in Feb had a hard time connecting it. Got it to work that night. Tried to use it again in March and all I see is a round circle!! Just horrible. I’ve uninstalled and reinstalled two times with NO success at all!!! VERY FRUSTRATED TO SAY THE LEAST!! ## Most critical reviews (10 lowest-rated) ### 1/5 — App doesn’t work at all *2026-05-18, version 1.7* App doesn’t work. Rendering the endoscope useless. ### 1/5 — NO LONGER WORKS! *2026-02-09, version 1.7* Basic app and it barely functions. DO NOT DOWNLOAD!! ### 1/5 — アプリに映らない *2025-12-06* 説明書通り、蓋を開いて、Wi-Fi接続して、アプリでスタートを押しても、黄色い画面のままです。カメラが接続されず、何も見えない、ただのゴミの棒です。 ### 1/5 — FRAUD *2025-12-02, version 1.7* This app connects to a video service that intends to charge you approximately $34.90 per month after two days. Totally a SCAM, because I bought a Smart Earpick otoscope from Amazon to connect an optical device to my phone for viewing the inside of my ear. This is not what was promised. Now I have to call my bank as well as Amazon to remove this illegal developer from my account. ### 1/5 — Antes estaba genial ahora no puedo ni abrir la aplicación *2025-08-14, version 1.7* No puedo abrir aplicación ### 1/5 — 怖い *2024-02-11* はっきり言います怖いです 発熱がすごい そしてWi-Fで繋げる色々怖いです あんまおすすめできません ### 1/5 — フリーズ *2023-12-16* 2秒くらい動くが、すぐフリーズする イライラする ### 1/5 — Awful *2023-12-11, version 1.7* Unable to use, will not work on iPhone and no updates or any help at all. ### 1/5 — Wi-Fi繋がらない *2023-11-23* Bluetooth接続ではなくWi-Fi接続なのでとても不便です。そのWi-Fi接続も最近うまくいかなくなりました。使えなくて困っています。 ### 1/5 — App malfunction *2023-11-11, version 1.7* I bought this device about an year ago and I only used it one time. It has been in the box practically brand new and I got it out last night to use it and there is no light coming on the device only the red light when I charge it. It is not showing up on wifi and I tried everything. The cap is off. I also deleted app off my iPhone and put back on and still nothing showing up on wifi. Because of this issue I can’t even use the device. ## Most praised reviews (10 highest-rated) ### 5/5 — Try this if the scope won’t connect to your phone *2024-09-12, version 1.7* If you are having trouble connecting to the “MZ” local network. Check the settings on your phone. Open the MZ Scope app setting and make sure the option for “access to Local Network” has been enabled. My wife was complaining the scope has broken and wasn’t working. She was about to throw it out and I fiddled with it and found out this was the problem. Somehow that option got disabled on her phone and the scope would not connect properly. SUGGESTION TO THE MAKER: maybe you can add this to the “instructions page”. ### 5/5 — Perfect *2024-02-15, version 1.7* Really helps clean my ears ### 5/5 — I use this all the time and it’s great *2023-10-10, version 1.7* So stop giving it 1 star please ### 5/5 — Connect to the camera first then start second *2022-11-23, version 1.2* Camera works fine with me. Just make sure first to connect the app/camera manually via the wifi settings. Then switch to the camera app and hit start. I didn’t use the other functions such as video recording etc. Recommended. ### 5/5 — Read Instructions and it works great! *2022-03-27, version 1.2* This is the coolest thing ever. The camera connects to the app effortlessly if you follow the instructions. I would first charge the device fully before use. Then open the wifi settings on your phone and connect to the device name MZscope, then turn off privacy for the MZscope wifi connection and lastly open the app. Waiting to open the app after connecting to wifi seems to be an important step. Once the app was open I pressed the big start button in the app and it worked instantly. Great product. Not sure what the bad reviews are about because it was so easy🤷🏽‍♀️ ### 5/5 — It worked then didn’t but it’s fixed *2022-02-17, version 1.2* This works very well for cleaning out the kids ears. I can’t see like I used to do it’s been a super handy tool. I was so upset because it quit working, the visual wouldn’t show up, there was just a yellow round screen in the app. Someone else mentioned security setting but I just uninstalled the app and reinstalled it and it works perfectly again! ### 5/5 — App works great *2022-01-14, version 1.2* Not sure why others were having issues, but it seems as though they fixed whatever bug there was. Just download the app, open the cap, then connect to device via wifi (“MZ Endoscope”), then go back to the app and press “START.” Pretty much follow the directions and you’ll be fine. ### 5/5 — No issues 1/2/22 *2022-01-03, version 1.2* Writing a review purely to negate the others, as I had no issue setting this up. iPhone 13 Pro Max, iOS 15.2. Works as advertised, easy to set up, easier to use. ### 5/5 — Works on iOS 15.0.2 *2022-01-01, version 1.2* Works after uninstalling and reinstalling app. (1) take cap off, (2) go to wifi settings and connect to MZ Endoscope (3) go to app (4) it’ll ask for some permissions, allow. ### 5/5 — Just read user Manuel! *2021-12-19, version 1.2* The app works perfect. Just read your user Manuel on your camera and do what it says.. worked within a couple mins of setting it up --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
