Hi @memes4u, Interesting product. I've spent some time reading about it and how the customers have responded in this regard. I'll sum up my findings in the form of pros and cons below:

Pros:

i. The lock has a nice design from the outside
ii. It's easy to set up
iii. You can even use it to lock your bag or suitcase
iv. The price is affordable

Cons:

i. The product has so many negative reviews
ii. The lock does not work on first try and several people have complained about it. Even at recognizing the voice and following all the steps, it often times does not open the door and keeps you waiting that's a worst thing in emergencies.
iii. Cable seems little thin so in my opinion, it's not 100% secure to reply on this lock.

I give it a 2.5 Star rating.
