Fingerprint Padlock for Gym Locker, High Security Smart Padlock, Digital Lock for Indoors and Outdoors, Safe with High Security, Bluetooth Equipped (Onyx Black)

I am extremely impressed with this smart padlock!It looks really, really good in my opinion, and the fingerprint sensor is one of the best I've used outside of a modern smartphone. It is surprisingly reliable and seems to work first time in most cases. It is made of metal (one review claimed it was plastic) and despite the pictures, the logo does not glow except for when you perform an action (eg. scanning fingerprint or remote unlock) which is a good thing and a relief actually, as it doesn't draw any unnecessary attention.In normal usage, the padlock automatically locks when you close it and can be unlocked by pressing your finger on the fingerprint scanner. It can also be unlocked via the app if you have any issues with the fingerprint detection.The app is well designed and nice to use. It allows remote unlock/lock, registering of fingerprints, tweaking the settings, the battery level as well as downloading logs, which shows a list of times and events such as when it was locked and unlocked and even failed attempts, so you can see if someone has tried to use it while you were away. One review said it doesn't show anything in the logs - it does. The trick is you have to click the sync button and it downloads the latest logs. It takes a few seconds to sync.There are apps for Android, iOS and the Apple watch, but no watch app for Android Wear which would have been neat, but not essential.I did have a weird issue with the Android app while setting up the first fingerprint (it claimed the device immediately timed out and then wouldn't register any fingerprints). I was getting worried for a bit but then it eventually started working normally and I've had no further problems since.It is rechargeable and charges via USB C which is just brilliant and how all smart devices should be.I'm a little skeptical of the security it provides. Is it as strong as a good metal padlock? I'm not sure. Maybe? I have a feeling it might not stand up to a lot of abuse, happy to be proven wrong here, but it seems to be at least good enough to use for most purposes such as a gym locker.The best part is the convenience. Since it's fingerprint based, you don't need to carry a key to open it (which at a gym is definitely a convenience) and you don't need to remember a pin as you would with a combination padlock. I'd say it's actually slightly faster to open than a key based padlock and significantly faster to open than a combination padlock, which means it's quick and easy and not a hassle every time you want to open the padlock.It is an expensive lock, the most expensive I've seen, but it's most likely the best smart padlock around and I am glad I got it.

Having to re order and ask for a refund on the first one as it’s come faulty. Managed to get it to sync to the app and then couldn’t update the firmware. Now the padlock has locked and I can’t get it open again. Raised a ticket with support and they have said have it replaced by Amazon.On the upside. The lock feels very good quality and perfect size for a gym locker which is what I intended it for. Shame it’s not working at the moment. I will update my review when the 2nd one arrives
