Highly satisfied with the service. They helped me choose the perfect size from the website. And then came over to install it.
This lock comes with superb features like security alarms and fingerprints unlock system. I am truly impressed.
This is a sleek design, and looks very nice on my door. Very happy to have bought it from here.
My door needed a new lock, and so I decided to get a digital one. Their service is awesome! They found a lock that would fit my door and installed it very nicely.
I liked the fingerprint digital lock. I usually forget the pin, and this one here is a saviour.
I was confused about the sizes of the lock but the customer service guided me very politely. They also came to my home for installation. Great service!
Great Product! Very happy with the service.
I was looking for a digital lock since long as my previous lock seemed to be knocked up. Could not find a better service or product. Work done very nicely.
I got too choose from the available sizes but I was confused. Their customer service helped me pick the perfect one for my door, and then they came in to install it. Very happy with their overall service.
5 Stars for this one! They have great service and the technician also provided some great tips on how to handle the lock with care.
I am highly satisfied with the product quality and price.
I am so happy to have bought this. I found the price comfortable. Good product as also gets installed on larger doors.
This lock size fits my large door. Thankfully, I found this one. Extremely satisfied with the installation service.
The digital door lock works very nicely. The installation was smoothly done by their technicians. Thanks!
The best part of this lock is that I can put in as many fingerprints as I like, up to 100. Just perfect for my big family. And the installation was done very nicely. Thanks!
This is really nice lock. I had another digital lock installed previously from some other company, but it turned out bad. This one is pretty impressive. Thanks for the good service.
Good thing they offer a larger lock cos our front door is slightly bigger than normal. At the same price too! The technicians took a longer time because of our metal door but they were very professional. The $40 for welding is a sum well-spent I feel, especially for the quality of work. Highly recommend!
Great that they offer two sizes for the basic lock. No complaints whatsoever. My family is so happy I finally got this
Super happy with the product and service. With this covid thing going around, the full door wipedown is super helpful. Big thanks for going the extra mile!
5 stars review! Shoutout to Lee the technician who was friendly and professional. Gave me loads of tips on how to take care of the lock and door.
Nothing bad to say about this. Pleased with everything
Who would have thought a digital lock was so game-changing? Getting home is a breeze now, so fast and convenient. Hope the lock lasts!
My family likes this lock better. We all have our fingerprints stored in. And feel more secure.
I highly recommend this to. The installation guys are super helpful and did their work perfectly well.
This is totally worth the price. Highly recommended service.
The digital door lock is fine quality. They came and installed it very nicely. And the size fits fine. Very good service.
5 stars for 5 in 1 lock! It is seamless and works smoothly. I love this.
Good product and beautiful sleek design. Love the features and totally impressive service.
Very happy with my order. I love the lock safety features and sleek design. Highly recommended.
Thanks a lot for such a great service. The product is easy to install on big doors too.
