Would you recommend Netgear ORBI?

I've had an ORBI RBK50 system installed in my house for over a year. My home is single story and about 3000 sq ft with concrete block construction and a stucco exterior. I also have an 4 car attached garage/shop and an outdoor living space with pool automation. I estimate the entire area covered by the ORBI at >5000 sq ft. I've had very good luck with the ORBI system. That's not to say it has been trouble-free. The initial set-up requred a bit of hassle to find the "Goldilocks" spot for the satellite and each firmware update seems to require a factory reset.

I recommend you purchase the ORBI at Costco and test it in your environment. If it doesn't meet your needs–return it and move on to another system. However, if you follow most of the hints/tips in this community, e.g., don't put the satellites too close, deconflict the 2.4 gHz & 5 gHz channels, factory reset after firmeare updates and manually configure your system, you'll find you can have a very stable, powerful WiFi system.  Good Luck!
