These wicks burn long and clean! I use only soy wax so I don't know how they'd burn with other kids of wax. But I've used them with different waxes and they're great.
-They do mushroom at the top so you have to trim them every time. That's the only reason for the 4 stars instead of 5. Some people don't trim their wicks so this will cause the candle wax to burn MUCH faster.
