Scummy, anti-consumer company
I bought a Lofree Num Pad & Calculator. After I got it, I checked the website and saw a firmware (v1.00.54.00) was available. I followed the instructions to flash it and it bricked my device. Emailed their support team and instead of helping me, they just deleted that web page. They said they "don't provide firmware" even though they obviously DID, so they won't give me the previous firmware file to fix my device. For reference, you can still see their former Downloads page if you search for it on Archive.org (actually, it's still indexed as the top result in Google search under "Lofree firmware" too).
