Review: Great concept and exceptional customer service. Extraordinarily responsive - Very happy with this purchase. And I have to say the customer service is outstanding even with the holidays. One of my speakers was not pairing. ChatGPT and I couldn’t get it to pair. I reached out on Christmas Eve Eve to customer support and they responded just after midnight on Christmas Eve. Their first suggestion didn’t work, but their second suggestion later on Christmas Eve did work. So far I am very pleased with the quality and sound and just the general concept of this set-up.
Review: Great sound quality - Absolutely love this system! Easy to use or connect multiple devices. We ordered an additional three speakers and everything is working together beautifully.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great concept and exceptional customer service. Extraordinarily responsive
*by A***R on December 25, 2025*

Very happy with this purchase. And I have to say the customer service is outstanding even with the holidays. One of my speakers was not pairing. ChatGPT and I couldn’t get it to pair. I reached out on Christmas Eve Eve to customer support and they responded just after midnight on Christmas Eve.

### ⭐⭐⭐⭐⭐ Great sound quality
*by J***R on December 11, 2025*

Absolutely love this system! Easy to use or connect multiple devices. We ordered an additional three speakers and everything is working together beautifully.

### ⭐⭐⭐⭐ Convenient and affordable, but easily affected by other nearby electronics.
*by C***Z on August 2, 2025*

I like the convenience of having sound throughout the house, and these speakers are more affordable than other brands. But they are very sensitive to other nearby electronic devices. If a computer, tablet, TV, etc. is located near a speaker, it can cause the speaker to make a crackling noise or even disconnect altogether, especially if the speaker shares a power outlet with the other electronic device. So you really need to experiment with the best placement of the speakers so as to eliminate these disruptions.
