    The Future of Padlocks

    Just ordered this about a week ago and was surprised how fast it actually came. Was on the phone with Phil and he is extremely knowledgeable and easy to talk to. The price seemed a little high for a lock, but I use it all the time. Once I got it I quickly realized why its priced where it is. I go to the gym frequently and am an idiot and forget my combo all the time or mix up the numbers so it got frustrating. With this I just unlock it from my phone, which I always have on me or if my girlfriend wants to borrow it I share it with her and all she had to do was download the app.

    Story Behind the One Star Value

    I am the type of person that never writes reviews on anything...... EVER. But I have a story I had to share. I am the type of girl that likes new things or things that I think are tech savvy and was looking for a cool gift for my boyfriend.... at the time. Anyway I ran across this site and saw this product and decided to give them a call. I ended up speaking to some guy named Hunter who gave me some details and I decided to buy it for my boyfriend. Long story short I gave him the gift he added me to the lock and basically ended the relationship by locking me out. The lock itself is super cool and savvy and definitely worth the price. I gave it one star in value because I can't use that lock anymore because he locked me out and it reminds me of that idiot. I decided I should share this story and definitely will be buying one soon.

    Sweet Lock

    I am a Mom and the reason I got this was to put a lock on the cabinet where the snacks are stored. I am trying to promote healthier eating. I have three children who have to have the sweetest tooth on planet earth. The reason that this product is so sweet is because I can monitor who unlocks the snack cabinet and the kids know that I know so it helps prevent them from eating so many sweets. Awesome product and it's going to keep this family healthier or at least try to.

    Absolutely No More Problems

    I would say I use a lock about everyday. I enjoy working out at my local health club. There was a long time where I was just against locks whatsoever and would suffer to get to the gym and only be wearing what I was going to workout in. Being that I live just outside Newark, NJ the weather can be unbearable sometimes. I decided to get a combination lock until someone broke into it. I never knew this but if after you run through your combo and open your lock if you shut it and don't turn it then the locking mechanism still be able to be opened. I learned that the hard way when someone took my wallet. So I decided to get a lock with a key until I lost it in the snow. If you have ever dropped something in the snow it is an absolute nightmare to try and find. So, I was looking for something new and came across this bad boy. First thought was $45!!!! No way. But, I did a little research saw that this was a probably the best price out there. Since then I have not lost my key in the snow and no one has broken into my locker. Lastly, it is by far the coolest lock anyone has brought to the gym. Absolutely Terrific Product!!!

    New Tech With No Complications

    I was intimidated by the new technology when I first saw it, but once I received it I quickly realized it was new tech just without the complications. I am a chemistry teacher and run the lab as well when students ask to go into the lab to grab equipment or what not, I grant them temporary access. This way I can monitor who has unlocked the lab. I once left my phone in the lab and couldn't remember the combination, but remembered when I purchased the lock the sales rep told me that if this happened I could just go to the website (masterlockvault.com) and change the manual password without having to cut the lock. Overall this is a terrific lock and I found it cheapest here even with shipping.
