I've had one for over 6 months, and I love it. No problems so far.

I had Schlage locks on two of my doors. Never got them to work right. This time I bought Kwikset Powerbolt2. I have one on my front door and it’s easy to install and easy to use. I just watched a YouTube video with my neighbor who helped install the first one. I purchased mine on Amazon.

I did install alkaline batteries, Duracell and did put them in correctly I did call Schlage and did get someone who seem more knowledgeable compared to past call center reps. She did not mention directly that they had issues with the lock but did say areas with high humidity, salt air etc. can cause condensation inside the lock warm humid air outside and dry cold air on the inside. Supposedly the newer models have improvement so I am getting a replacement direct from the factory with all the latest upgrades.
I'll have to see when I get the lock
