To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
This system works great, but there were no usable instructions (in fact, there were conflicting instructions when you include other add-ons). It took me some time to sort this out, and I had to solder a custom board to bridge all the connections, but once setup -- works great! Unbeatable price. Highly recommended for the DIY-types (5-stars). Not recommended for the plug-and-play types (2-stars). Gave it a 4 by way of representative average.
I pre-assembled the unit, programming the cards, key fobs and keypad to my specifications. Everything worked fine. When I went to assemble the unit to my door, the lock would not release. The codes I set up for the keypad worked because the geeen light came on, but the lock would not release. I tried the key tags, cards and they worked but the lock still would not release. I disassembled the wiring and took my time again to make sure everything was wired correctly, using low- voltage wire for the lock still rending the same result. Thankful Amazon is refunding a portion of what I paid. Could not contact the manufacturer after speaking with Amazon tech.
I finished installing this system at a client's house and we are very happy with how it works. I would give it 5 stars but instructions suck. It was easy for me since I know a little bit of this and that. I will be purchasing this again.
