I was looking for a smart lock and decided on this one because of the many positive comments. I am really impressed with the performance of this product, it meets and exceeds my expectations. I really don't understand the few negative comments here. I installed it in no time, it works great. If you want a quality lock, COLOSUS is for you.

The installation of this lock was my only problem, although it does come with an installation manual, but I still needed the YouTube videos. Changing the old door lock with this one is the best decision I've made, I feel more secure now. COLOSUS is very good quality, it is plastic but it is not what you think, it is very sturdy. I have been using mine for almost a year now and it is still as good as new. I am very satisfied with this item. I can't recommend it enough.

I often go on business trips and in those moments, I need my sister to guard my house and keep my dog company, as you know, we now live in total insecurity. Since she often loses her key, I opted for a smart lock. She can now enter my house with her fingerprint, it reassures me a lot. She also feels safer with COLOSUS and my dog. I think I'm going to buy one for my parents too.
