@APOM yes, so I did an Amazon return citing this reason.  Their listing stated HomeCare, but the product I received had HomeShield.
Looking back, I likely wouldn't have used the features, but just felt deceived \ tricked when purchasing.  If the listing had of been updated, I wouldn't have felt tricked, but I went exploring for the features in the listing.

You will find that the M5 is now HomeShield NOT HomeCare other than that I don't know the specs.
 

On the x20, they released a new hardware model, halved the CPU cores, dropped the CPU clock speed, moved features to a subscription model (ie: HomeCare to HomeShield) and didn't lower the price.

I'll likely buy the unit gain, as it seemed decent, but wait for a sale as I can't justify full price with these changes.

So YES I was tricked, but it's not model specific, looks to be across all their products.

Thank-you for the correction, I must have mis-read the technical specs of the M5. The Amazon listing from the "TP-Link store" for the x20 still shows HomeCare with a QuadCore CPU. You could be right about the performance, but buyers feel tricked when they purchase a product and the actual specifications have change. Like if CPU doesn't matter, then why mention it.
