Overall experiences with this charger?

I was only looking for a 4 Slot charger for the 4x18650 lights I’m accumulating.

This charger can charge 4 Slots at 2A this is what caught my eye.

Should I be looking at analyzing chargers so I will know the health of my cells?

Thank you for any info you provide.
