Best investment!
I purchased this is 2018 and have yet to change the battery! Aside from that, it’s the best thing I’ve had to remind me to drink water. I’m never dehydrated anymore! The only con about this is having to pay close attention so it doesn’t pop off the band. But if you’re always conscious of that, there are no problems at all!! I love this thing and highly recommend!
