1. The black cap is much more difficult to open compared to the red cap previously used.
2. The slit pour vent ( I don’t know what you call it) once you take the cap off is not as good as the little squares previously used. The fuel pours outside of the fuel tray, making a small funnel necessary. A real inconvenience.
3. While the current fuel order seems to produce higher flames, I’ve timed the actual burn time to slightly +/- two hours. Previously ordered fuel from Amazon generally burned from 2 to 2 1/2, sometimes almost 3 hours. This means that value for dollar is decreased.
4. Is only a three pack now available from Amazon?
