Not that matches important

If you have more money, you can buy this. It’s not necessary and it’s not going to work without Wi-Fi.

good

I absolutely love Vivosun equipment and products and the app to control and monitor everything on it is awesome. But they're shipping sucks and the customer service is just OK at best. Most all their products are on Amazon so just order from here you can still use the discount codes and have it shipped within one or two days.
