Their life span is a few months max. Takes forever to charge and charge only lasts most of the day. Not 2 days as explained by numerous platforms.

The facial recognition works for me 3 out of 4 times. The charge lasts a long time. And this has a bigger battery, which is nice.

The fingerprint reader is horrible. It works occasionally. It's slow and glitchy. Just don't buy one from this seller expecting it to be unlocked.
