No longer works after the warranty expires Nach Ablauf der Garantie funktioniert nicht mehr. Die gleiche Erfahrung mit zwei Schlösser gemacht. Definitiv keine Kaufempfehlung. No longer works after the warranty expires. I had the same experience with two locks. Definitely not recommended to buy.

Battery with short life I made a very similar experience to what is described in the previous reviews: I bought 4 Locks 3 years ago and all of them are dead now and can’t be charged anymore. „Support“ says its a battery issue but they are not willing to replace at least 2 of them after the warranty period referring to „company policy“.

Good idea, bad quality & customer support Basically, I find the lock and the idea very good. I have three of them, but bought directly from Ziilock. Two of them still work perfectly incl. fingerprint opening. The Bluetooth connection is, as mentioned in some other reviews already okay, but has no special range, means only works in the immediate vicinity of 0 - 5 m. The holder itself is also quite robust, only the fixing straps are a bit slack and torn on one lock after just one year. With the third lock I had a problem. I had bought it 1.5 years ago and put it in the closet, because I wanted to use it for my new bike. Then, unfortunately, everything took a little longer and I got the wheel only now. When I wanted to install the ZiiLock (and took it out of the still unopened package)) the battery would not charge - no matter how many cables I tried. The answer from Customer Service was very terse: Yes, it happens from time to time that the battery is defective. However, it cannot be replaced and the warranty has unfortunately already expired. ...and so I now have a more expensive "dumb" bike lock. IMPORTANT: Check the batteries as soon as you get it and note that there is only 1 year warranty. That would not have happened to me with ABUS.

Great idea but piece of junk Bought this lock a year ago for a bike at my second home. Loved it when I first got it. When i returned this summer, the battery was dead and would not charge. Customer (not) service said too bad. Battery is not replaceable. Do not buy this lock. Great idea but total piece of junk. Waste of time and money.
