I gave 1 star for the scent as they didn't have any when burnt. Could smell them lovely in the box. The burn time on the ones I had was between 8 and 9.5 hours. Which I very shocked at. Given that some of the reviews are very negative I'd buy and see what they are like for yourself. I like them even though they don't have much sent. I put mine in a plain glass jar. And one lut the whole room quite brightly will be great if we have power cuts this winter. Would i reccomend them. Yes if you luke unscented but if you like strong scents I don't think they are for you.. But like everything you have to try for yourself. I'm buying more as they were on for me.
