Very sturdy and high quality. Phone performance:I compared how the Bose and the Sony sounded when recording and playing back my voice with a fan running in the background. The waterproof fabric has cracked on the sides along the sole. My son requested this for Christmas. The speaker can also be set up to display device notifications. You hear everything but hard to tell where it?s coming from. I have tested and tested and tested wireless speakers -- this is by and far the best. I would definitely recommend to other chefs! The case appears durable and has a nice digital readout that appears through the plastic. I bought these because I have a tiny kitchen and needed to go vertical with storage.
