### 1/5 — Upgrade ruined the lock

*2026-08-01, version 1.4.3*

Lock was working perfectly. Then they created a firmware update. The update doesn’t work and the lock won’t work without the update. Frustrating

### 5/5 — Works as advertised

*2024-05-10, version 1.4.3*

I received and set up two of these locks today, and they work exactly as described. Yes, the English could use some revision in many areas of the instructions, but I didn’t even need to read them as the set up was basic for anyone who has ever set up a fingerprint on an iPhone. So far I am happy with this purchase.

### 3/5 — Apple Watch Please

*2024-04-21, version 1.4.3*

Great lock but need Apple Watch support

### 1/5 — App

*2024-04-17, version 1.4.3*

The lock works ok but the app is terrible.  It will not allow you to add friends or send them an invite.  It just says user does not exist everytime.

### 4/5 — Nice product

*2023-12-15, version 1.4.3*

The rock is pretty easy to use. However, the unfortunate point is that it is not completely remotely used by the app in fact, when you go and try and use the lock and unlock it using the app, it just says to press the button on the Smart Lock to wake it up, however putting your fingerprint will unlock the lock and it will keep it connected, but I’m not sure why even have the app to unlock the app, I think they should fix it other than that it works pretty well

### 5/5 — Megafeis lock

*2023-09-24, version 1.4.3*

Awesome lock, works really well with fingerprint identification, my only suggestion would be to update the software so you could add the app on the Apple Watch

### 4/5 — Good, would be great if connected to Apple Watch

*2023-09-24, version 1.4.3*

This is a great lock for gym lockers, there are no combos to remember or keys to carry. The only thing is if your phone is locked in the locker, you have no backup if the fingerprint fails. It would be great if the app also works on the smart watch as an emergency backup.

### 1/5 — Bad. Very bad lock!!

*2023-08-14, version 1.4.3*

Couldn’t get it to connect with my phone through Bluetooth. 1 out of 10 tries to get it to connect and it didn’t stay connected. Fully charged after getting, but battery drained to 3% in less than a week. Had an upgrade but it wouldn’t allow the upgrade. Absolute garbage. Wouldn’t trust leaving my valuables with this lock.

### 5/5 — Works perfectly!!!!

*2023-07-24, version 1.4.3*

This thing is so simple that you can’t mess it up which means that if it’s defective, that would be obvious as well. Download the app, register a new account, add device, clear any precious fingerprints, add my fingerprint, done.

### 1/5 — This is NOT dead by daylight

*2023-07-02, version 1.4.3*

Idk what kind of prank this is but this is not dbd
