I bought this particular model in 2017 and have never had a problem with it. I rarely need to charge it, MAYBE once a month if not longer (I only use this product in the shower for about 15 minutes about 4 times a week). It doesn't take long to charge to 100% either. The biggest complaint is probably that the model I have 4 years ago doesn't "expire" if you don't play audio on it for a while. So if you forget to turn it off yourself, it just stays on. Love this thing though. It's been 4 years and it still works great!
