We purchased this for our Airbnb and really wanted to love this lock but unfortunately the first one stopped working and was past the warranty. We purchased a 2nd one and keep having the same problems with the batteries not lasting. We've tried everything, even turning off the indicator light but the batteries just won't hold up. In another Airbnb that we own, we have a keyless lock from a different company and haven't had to change the batteries at all. It's really unfortunate and I feel that this is an issue the company really needs to address. I'm not buying another one and if this one fails then I'll be forced to start using other products.
