So far no issues with the speaker. Sounds great. Only drawback I see if the inability to pair to older versions of turtle box and the charger not being USB-C for more compatibility and not having to carry/keep track of the charger.
I have really enjoyed using my new Turtlebox Grande! The first time used during an outside bbq, everyone was extremely impressed at how good the music sounded. I was able to set it up without worrying about anything happening to it due to its ruggedness.
Amazing speakers. Battery life is ridiculous... sound is exactly what I've been missing in all my other outdoor Bluetooth boxes (well the aiwa exos 9 is very comparable). Love the ruggedness which the aiwa boxes couldn't touch. Expensive? Yup, but I'm feeling zero buyers remorse. If you can handle the cost I see no reason to not buy... assuming you are in the market for this sort of product
