Flow cells are 1000$ each (unless you buy a lot of them), the sequencer is basically a USB dongle with a uC in it and all the important stuff is in the flow cell. Flow cells are basically disposable (but you mail them back). You get one-ish use out of a flow cell though they can be "washed" and realoaded.

Reagent kits run a few hundred dollars depending on what your doing and you get several uses out of them.

IIRC it's not certified for use as a medical diagnostics device so it's "research only".

It's a nice system with great (none) upfront costs that has a lot of potential. But read quality and quanity per dollar aren't as good as what we get with our NextSeq (which by contrast costs something crazy like 300-400k)
