This piece of garbage will most likely foil the user more often than any thief, requiring the user to destroy it in the process. Several scenarios (very likely) are in mind:
1. I can see someone forgetting to charge the battery, or forgetting the lock on their luggage for several months. When they try and use it, it will be discharged and who knows how good the battery is and whether it will keep a charge, and for how long? There is built-in obsolescence because of the unknown quality of the battery inside.
2. The other issue is the USB port itself, could it be used to defeat or at least bugger-up the battery also? Let's say you plug in a little USB dongle that shorts out the charging pins? I would hope there is some electrical protection but if someone wants to just screw with you, they could blow it electronically or ruin the port, or stick some "gum" inside just to piss you off.
3. They show it on a bike (WHAT A JOKE!) but is this thing going to stand up to rain? How waterproof is it, and could that ruin the electronics in it? If it doesn't ruin the electronics, will it ruin the USB port? I assume there is a rubber flap over the USB port but there may be space around where the cable enters the lock to allow water.
4. With all the videos now available of the lock being opened and the weaknesses known (and the manual on how to reset), and the inside on how it works and how the cable is "screwed" into the other end, etc... (like the video linked in the previous posting), who will really be surprised when their relatively expensive lock is defeated?
5. The fingerprint sensor seems to be unreliable and so I imagine that a user may have issues with it and eventually get defeated out of their own lock. Every video seems to show people pressing on it multiple times, it not registering, etc. Another malfunction point to add to the many modes of failure.
There are so many things wrong with this lock, it is unbelievable that anyone would even want to buy it. It is a case of "smart" technology applied in a completely wrong situation. There are other smart locks, electronic, blue-tooth enabled, etc... that do have interesting features and add innovation to the industry, but this lock is NOT it. There are so many more effective options that are less costly and a better deterrent than this lock.
In fact, you are probably better buying 3-4 U-Locks with the same money... at least it will add more time and be more obvious someone is stealing your bike, in case it is a public area somebody may at least notice and stop them. And if the whole point of this is not to require keys, then get several COMBINATION locks with chains/cables if needed. Either way they would require heavier tools to cut than this FIPILOCK garbage toy:
