Master Lock 4401EURLHEC Bluetooth Smart Padlock for Professional and Private Use, Outdoor, Long Shackle,Black

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.

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 isn’t 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.

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

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.

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 (había 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 batería recargable iba perdiendo carga rápidamente).

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.
