I think any working Go pro is worth having if it can be had for a reasonable price. I’ve had mine for 4 years and don’t have a good enough reason to get a newer one . Love the quality of the picture, user friendly interface, long list of accessories available even though I have a ton already. If your into photography or videos I recommend getting one. BUT, if your buying one used, I would want to see it work before I pop on it. I rarely buy used electronics. Find a good deal on new from a reputable source.
