Customers say
Customers find the padlock easy to set up and appreciate its robust build quality. However, the lock functionality receives mixed feedback – while unlocking and locking is easy, some report it won’t stay latched shut. Moreover, the battery life and value for money get negative reviews, with customers finding it expensive and reporting issues with low power.

Terrible, please see updates below
While I do like the idea of this lock it is let down by issues.Only a couple of times as the locked worked on the 1st press of the button to unlock, this normally requires 2 or 3 presses before it turns green to unlock, please note after each press you do have to wait for the blue light to go out before trying again, and on a few times I have had to open the master lock app on my iPhone before it would unlock, I will be keeping this lock even thought it only works as per design around 10% of the time and just hope a firmware or app update resolve these issues, the lock itself does feel very sturdy and has a good weight.UpdateI have removed one more star, battery has lasted around 6 weeks, had to use a 9v battery this morning to open the lock, this lock gets opened no more than 5 times a week, so really would have expected longer then this, I would have returned it returns window was still open, I cannot recommend this product, while a great idea it is plagued with software issues that make it less convenient then using a good old key, there has been no firmware or software update in the 6 weeks I have owned the product so far.Further UpdateI have just tried to open the lock this morning and yet again battery was flat (lock was purchased end of Sept 2017), please note the batteries I used to replace was energizer Lithium, so not a cheap option, I do have low battery alert turned on and had no warning both times battery has gone flat.I really would not recommend this product, reverted back to my old padlock.I will be reaching out to master lock for a refund, they may send a replacement which i will test further, however for the time being I would really recommend saving your money and sticking with a old fashioned padlock for now.

Great lock – recommended
I purchased two of these for a beach hut.Really great build quality. Works brilliantly. No complaints at all.The application is really good, and permits shared access to the padlocks. You can configure temporary or permanent access.Really like the feature of a push button code if Bluetooth is not available for any reason.All in all an excellent product – I would purchase again.

Make sure the lock you buy has enough capacity!
We needed a multi user lock for access to our tennis courts, no good having a combination lock as none members were accessing the courts previously as the combination became known. Combined with our booking system this was to give us track and trace for Covid-19.Fine except that the lock version sold here only takes up to 15 users which isnât advertised anywhere.We therefore had to get the lock upgraded for more users which was a bit of a pain as supposedly we had to phone the office in America to pay for this. After a couple of expensive Phone attempts being put on hold we found the European office Phone number and email, which was incorrect on the internet registration system, by phoning the UK office and managed , after complaining Re the cost already involved of Phoning America, to get a free upgrade-well done and thank you MasterlockThe Bluetooth system now working well giving us the user traceability we needed and meaning the courts are only accessible to our members.

Lock will not work in the rain!!!
Liked: Convenience.Dislike: After 2 months of use, the lock stopped working, and only after a lot of hassle did I eventually manage to get it unlocked. The fact that it is so unreliable makes it useless.It just stopped working, no low battery warning or email, which is what the instructions said would happen.It is unacceptable to have a lock just STOP WORKING! Especially when it is SO EXPENSIVE!!It is supposed to be suitable for outside use, but this is not the case.

No giest acess
It is impossible to allow guest acess. I have spent hours trying to set this feature up but just gave up.

AMAZON RESALE = USELESS LOCK
Amazon resale useless – states comes in original packaging (activation code on original packaging) but it doesnt, rendering the lock useless. Was told to contact masterlock but I’d have more chance of getting a reply from God himself.

Excellent product, easy setup and configuration
I purchased this item, as i hate having lots of keys around, and i love using my phone for as much as possible.On first impressions its really well built, it was easy to setup and pair with my iphone without any issues.Unlocking and locking is easy, and after many operations its still working fine.Setting up with the iphone was easy, but a little more tricky with Android,I am not so familar with android , so that could be down to me.I would recommend this product. Shame about the price, its pretty expensive compare to the USA price.

Déjà 2 ans que je l’ai, toujours pas changé la pile d’origine malgré de nombreuses utilisations la semaine (vestiaires du boulot). Le système bluetooth fonctionne bien aussi. Le système lumineux aussi qui nous indique le niveau de la pile.

El candado es bastante grande pero de momento es el único que ha aguantado lluvia y nieve en el exterior. La pila (CR2) aguanta mucho tiempo. En el iPhone hay que actualizar la app a la última versión porque la anterior no conectaba con bluetooth (habÃa que abrirlo con la clave de teclas). En comparación, un Dog&Bone Padlock duró 12 horas antes de morir y un Quicklock (no vendido en España) unos seis meses (aunque el problema de éste es que la baterÃa recargable iba perdiendo carga rápidamente).

Requires an app that is unavailable in the UAE. This item should not be for sale on Amazon UAE! Its now an overpriced paperweight.

Als Eigentümer des Schosses kann man mit Eigentümer bestimmen und deren Zugang sehr gut einstellen und muss nicht selbst am Schloss physisch sein um das einzustellen. Man kann es auch mit einer Tastenkombination öffnen.

Har köpt 4 likadana lÃ¥s, alla har slutat fungera efter nÃ¥got Ã¥r.Köp istället nya modellen 6400, mycket bättre kvalitet och funkar klockrent…
