I was quite pleased with the quality of this product! Feels very hefty and secure. Setting it up? Personally, It was a bit confusing reading by the directions, but it was managable and I eventually got it solved. I have been using this on my front door for a few days now with minimum issues. I have ran into the knob being a bit stuck at times and the code keys being a bit stiff, but I think that's just normal with this mechanism. **now i apologize for this next part since i am no expert in writing nor technology, I'm just an everyday airhead, but bear with me** How the code entry works was a bit different than I initially thought recivieving this product (instead of most code entries being entered in by a string of numbers in a specific order ex. 1-2-3-4-1 This product uses a select number of characters and a mechanism that only needs the certain character to be selected once Ex. Just selecting 1 2 3 and 4 dosent matter how many times you press the button or what order) Overall, Id reccomend this lock for something like a gate or a closet. Yes, It's secure enough for a front door or whatnot, but after using it on my front door for a few days, I feel like it's just \"not secure enough\" for a front door ((or maybe im just the paranoid type))
