Purchase this Mesh System. Also purchased their security suite. Couldn't log into Surfshark using TP-Link android app. Talked to Surfshark and they said they don't list it as a certified model for their VPN. Not sure why it's in the Deco app for quick setup. Reached out to TP-Link. Tech Support took forever to ask for info I sent them the first time. Just gave up and bought a different system. I purchased the Deco because TP-Link is supposed to be known for their support. That's why I purchased their Archer routers for so many years. Can't say I'll go back.
