Luxform Lighting Samba Solar LED Hanging Lantern, Black

We own one of each in the range (salsa, Samba, jazz and flamenco). We've had around a month now.Positives* Look very sleek, modern and on trend* Give off a nice glow* Easy to install* Look nice in a row of four different styles* Good price.* Lightweight.Negatives* Rust has appeared on one already just a month in.* The jazz has a plastic bulb casing which is round not like the eddison style shown.* Moisture has got in to the jazz ones (we have two of these and both have done the same). I suspect because they are plastic and not sealed as well.* Within a week the lights have been intermittent as to which ones have come on at night (despite all being in the same spot to charge through the day). I've emailed luxform direct about this.
