I run mine on Boost all the time and still get close to four weeks without a problem, so maybe it varies by unit or how often you open the fridge. Could be worth letting it fully die and then doing a complete charge to reset the battery indicator.
Glad it’s not just me then. I noticed the same thing on some green highway signs, they almost looked like they had a weird tint to them for a second. Doesn’t bother me enough to stop using them, but I did wonder if I had a bad pair or something.
Honestly, I wouldn’t worry about WiFi at all. Mine just connects to my phone through Bluetooth and that’s it. It saves everything locally and syncs later.
Alright, thanks for all the replies everyone. Sounds about like I figured, but it’s helpful to hear from people who actually use it. I think I’ll just stick with my regular fan for now and save the money.
