Still has a poor UI for seeing the data, especially past data. A previous update made it so you cannot go back in history to view data. The data is more difficult to read as it now only shows it in a small portion of the view where before it was pretty much a full screen. That and having to sign back in every single day is a pain, at least keep it signed in longer than 24 hours.

I just bought a particle readers and am trying to register my account but it's broken. Given that the update notes say "now fixed issues with new login registration" but it's not fixed, this is probably not the company for me. If you can't figure out how to make a login and registration on an app work, I have no confidence in your product. Fix it now before I return this device! I didn't spend $200 for a device and online service that won't work. I haven't even tested the product yet, sheesh!!

Update: the accuracy is horrid. The local big expert monitors like Air now, AccuWeather, etc are saying the AQi is about 30, all consistent. This unit is way off when I take it outside at 76. Accuracy is very poor. Not worth even a third of the price. Unable to register. There seems to be problems with my username. I have no idea what is wrong with it. The rejection message is incomplete. The response from Elitech is gobbledygook. Elitech is not serious.
