    • Very nice and sturdy lock
Easy-ish setup through the IOS app and the lock is very sturdy. The user experience leaves a bit to be desired because the app sends you one code via e-mail and one code via text message at the same time. You will be inclined to enter the code from the text message first but you will be wrong. You have to enter the e-mail code first and then after that it will ask you to enter the code from the text message. Then you have to enter the activation code. The app shows you an image of the box as it appears on the packaging and you will try to click on it several times before you realize that the app wants you to enter the activation code in the textbox above the image and not on the image itself. I bought this to go on a Lifetime shed in my back yard. My only complaint is that it is slightly too long and a little too thick to fit in the narrow holes for my shed. I can get it on with some maneuvering but I would prefer not to have to. Aside from that, looks and feels like a quality product and works as advertised. I have been using it for two days so far. I am giving it 5 stars because I am rating the lock itself and not the usability of the application I couldn't find a way for my wife to have permanent access to the lock with her own account, so she ended up signing into my account on her phone. This works but is not ideal. ... show more

    • Unreliable: works sometimes, more often not.
I saw all the negative reviews of this outdoor bluetooth lock but also the positive reviews, so I decided to give it a try. Initial setup went fine. I installed the iOS app, setup the lock, and tested it a few times. The lock worked exactly as advertised, so then I put it on our gate and tested again. It worked, again as advertised. Then, preparing to show my wife how to use the lock -- now locked on the gate, I tried to unlock it and it wouldn't unlock. I could hear the triple-click indicating that the lock was "unlocked", but no matter how hard I pulled on the shank, the lock wouldn't open. Then the sound of the single-click indicated that the lock was locked. So I called Master Lock Customer Service. After several minutes on hold listening to music, I was able to talk to a gentleman who assured me that if I was hearing the triple-click (which I was), then the lock was unlocked and all I had to do was "really yank on it" and it would open. So I tried that a few times and on the last try it opened! At this point, I removed the lock from the gate and took it back inside the house to test it more. I locked it again, and again unlocked it -- once. But then I locked it one more time and this time could not unlock it no matter how hard I pulled on it. My conclusion after all this is that the lock works sometimes but often does not. This was very disappointing because my previous experience with Master locks has been wonderful. Anyway, I decided to return this bluetooth lock and stick with the tried-and-true manual key-type lock that has always worked so well for me: Master Lock Padlock, Magnum Stainless Steel Discus Lock, 3-1/8 in. Wide. ... show more

    • Good quality good price very cool!
Very sturdy lock with for the most part very well thought out features. In addition to that I also think that it has the best price in its class. The app could be more intuitive and I still haven't found how to revoke or modify temporary access and it should be made more clear that IF the primary owners phone is within Bluetooth range that a setting needs to be selected to prevent opening. For instance if the lock is on a pool cage and the phone is in Bluetooth range and powered - a child could still push the button on the lock to open it. Or if it's on a shed or something -- say in the middle of the night an intruder could do the same. It is preventable with a setting but I figured it out by stumbling on it. I'll be ordering more! ... show more

    • Useful Lock
Works great. I gave it a 4-star because the app could be better. While it works great on my phone, I find that sharing access (like with my wife) so others can access it via the app on their phone is problematic. She is still unable to access. **** UPDATED 12/26/2017 **** Master Lock customer support responded to me after I initiated a support request on their website. They got back to me this morning with troubleshooting instructions. I was able to follow it. Apparently I had to recalibrate the lock (done this before, but did not uninstall the app from my phone) and it worked. Adding 1 star back to rating since customer support was good. It will not get a 5 star unless the app is improved. **** UPDATED 12/21/2017 **** I purchased this lock in November 2016. It has been working well, except fort the app. Anyway, I've noticed that lately I have been having to go into locker mode to manually enter the combination to unlock it. I figured it may have been the battery running low, so now that I'm off for the holidays, I decided to tinker with it. I changed the battery and fussed with it as much as I can. It looks like the Bluetooth unit is no longer working and I'm just shy past the 1 year warranty. I'm stuck with using it in locker mode. I'll see if I can get MasterLock to replace it under warranty and will provide an update if they do. ... show more
