It's good news and I know you guys probably had no input in how it was sold but £5 a month for something that should be included for free (bearing in mind EE is more expensive than everywhere else) is a letdown.
Right now if you want 150 Mbps it's £35.99 from EE. Add this and you're paying £40.99 for 150 Mbps. Pretty ridiculous when you consider that TalkTalk does 150 Mbps for £28 and that would also give you access to sqm via the eero.
Tbh I haven't looked into FTTP and the benefits of sqm on those lines but surely it's almost not needed when you get to the 500 Mbps packages and beyond?
