Something to think about. ST wifi is dual band. One 5ghz and I've 2. 4ghz band. If you use it as a wireless mesh, devices connected to the repeaters will have their speeds cut in half because the backhaul is shared with the 5ghz band. If you can wire the backhaul (connect the main router to the repeaters with a wire), I'd say go for it. If you're relying on it to work wirelessly, I'd recommend looking for a tri-band mesh system like the Orbi Rbk50. Tri-band has a 2nd 5ghz antenna dedicated to communication with the router so speeds don't suffer.
