The speaker won't last more than a year. The batteries won't hold a charge anymore. It sounds great but their downfall is the batteries. We also have a UE Megaboom that is 8 years old and it still works and holds a good charge.
It's good to see two 18650s where so many devices have just the one (despite having space for more). The drivers must be high grade because they sound a lot better than the ones in a Tronsmart Trip.
