Absolute junk. Buy a quality through a better supplier

I bought the S7 mesh system, worked well for a week and bought a second set to add on. Then the company did a firmware upgrade and now it’s constant issues. The system is useless, often it won’t connect and requires numerous reboots. Just read all the negative reviews on Google and HelloPeter. This is junk, rather buy a quality system from another supplier. Edward at TP-Link has no concept of client services. He promises to return calls but never does.. or maybe he is overwhelmed with so many dissatisfied customers
