I do like the glow these lights give out, they look very pretty & cosy!
However in order to get a decent amount of light & to stay alight for a good amount of time you need to make sure these lights have good exposure to the sun, all day. No good placing them where they will be shaded at all through the day! The spikes are a bit flimsy too, so make sure you push them deep into the ground otherwise they sit wonky!
