I needed 10 post lights for a new fence so I ordered 2 packs of 6 allowing to have 2 spares for the future when these inevitably fail. 1 turned up broken, being shipped from China though I kind of expected that. However what I didn't expect is for the first one to stop working after only 2 days. It now only works on cool white, where as all the others are on warm. The working ones have also started to fill with water after a small amount of rain. So I'm already using both of my spares, this doesn't fill me with confidence. $2 Bunnings solar lights generally at least last a year...
Also the sizing on these is a bit confusing, so I'll let you know that without the adaptor the light will fit nicely on a 100mmx100mm post. Just be careful though as lots of 100x100's you buy will actually be 100x103, and then these won't fit without modification.
I wouldn't buy these again and have pretty much just accepted that I've wasted $180 urgh.

These lights are poor quality. Although all six were fully charged during the day, two of them stopped working the second night. Just requested a return code.

Love these. Came late, but they work well! First order didn’t work so well. But love em now😍

Got this as a gift for my mother in law who loves butterflies. This was such a beautiful light. The solar works instantly and is still going strong. It is great metal, doesn’t seem like it will rust. Gives off a beautiful light, not to bright.
