We live off the grid and use these solar lanterns every night. The solar charge durations are as advertised and we love the waterproof inflatable part. One of our lights had an on/off switch malfunction after 6 months (the button just stopped working) and several don't inflate after 2-3 years of use but we still think these are excellent lights and continue to buy a few more each year! I wish we could have some of our older ones repaired.
