Edge 510 has seen ~3 years use. Holds charge for ~6-7 hrs. depending upon how many sensors are connected. No significant issues other than the fact it's a bit older.
Fenix 5 was used for 2 years. Holds charge for 7-8 days depending upon use - prior to upgrading I was training ~10 hrs. p/week and only charged it 1x p/week.
$250 for both (OBO) - $125 for Edge 510 / $175 for Fenix 5
