I bought this because, like others, I have kids playing and watching stuff online and was constantly being moaned at because the Wifi was "glitchy." Set up was very straightforward with the app and it just works. I have decent wifi all round and added parental control.

The product works really well. The wifi is now very strong in my house (3 floors). And we get a good signal outside too. I had issues installing at first. The app wouldn't find the units. I then used my wife's phone and it worked. About 30 mins to get it up.

The router node is fast and shows good range, but the satellite node's performance is merely average. Moreover, this system lacks the anti-malware tools that you get with other Deco systems. That said, its $180 price will appeal to budget-conscious users looking to fill wireless dead zones.

Reasonably priced; Easy to install and manage; Solid router performance; Strong parental controls

Lacks malware protection; Middling satellite performance

After struggling with intermittent/weak WiFi for years the change to this bit of kit was a revelation! In summary my WiFi signal was interfering with those belonging to my many neighbours for many years and was resulting in upload/download speeds of circa 500kbs - despite me having fibre broadband.

The TP-Link Deco M4 is rarely good enough to justify itself as a replacement for the M5, and it makes one-too-many software compromises for it to hold up as the budget-friendly alternative either.

Cheaper than Deco M5; Easy to set up

Slightly slower than M5; Bigger than M5

When it comes to value the Deco M4 hits all points bringing a cost effective dual band mesh solution to the masses.
