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.

The user name must be 6-50 characters, you can enter letters, numbers, underscores, but cannot start with numbers or underscores

I am unable to use this app. It will not allow me to create an account. It tells me my email address is incorrect (how can that be if I'm signing up now? I'm telling you the email) and that my user name can only be in Chinese characters. I've tried re-installing, doesn't help. I will have to return the device if I am unable to use the app. The developer had replied but it is not helpful. I am following the correct rules for a user name. The app says my email is incorrect and won't send a code.
