New York Pura Smart Home Fragrance Diffuser Refill Duo

The whole Pura Diffuser idea sounds pretty cool...control it with your iphone app! Until you have to use it . It is ridiculously complicated as you cannot turn it off and on without your phone. Then, I mistakenly deleted the two fragrances that were in the device. Now, you have to start all over again, going through settings, scanning the codes, logging in, etc. The whole thing is waaay too complicated for what it is. Yes, the Nest fragrances are nice , but NOT that much nicer than any inexpensive wall diffuser . And, my husband's concern: why does your air freshener need access to your wifi? What other info is it sending back to Nest? Not thrilled with this purchase and it's being returned. That said, I hope Nest brings back the regular Hearth reed diffuser in the glass bottle.
