What kinda Fitbit is this

I was wondering what Fitbit this is before I buy it second hand

Hi @Joshman15906  the Flex was a sweet little device, but I'd not want to buy one second hand. It has been replaced by the Alta series, which was replaced by the Inspire series. It's fairly old and the firmware isn't being updated. If you get a good deal on the price and want to try, then get it. You can get a new Inspire, complete with warranty, for $50.

I’m not sure how to upload pictures of what I’m looking at buying

You posted this in the Flex area. Ok, then click here - click - and look at the pictures of all the FItbits.
