I’m quite pleased with this stuff. Easy to cut and fit into the tank and does increase burn time. Not massively but can definitely notice the difference. For the price it’s well worth it.

have to be cut down to size but work well increase your burning time by about 20%

Does the job

Great value for money , delivery great

As a new owner of a bio ethanol. I thought I would try ghis to see if it extended the Burning time. Basically I cut this to fit into fuel chamber and pressed down. I would say after a couple of uses and closing the damper a little we managed to get nearly 4 hours burn time So worth doing.

Good value

It definitely extends the length of time my bio fuel burns. Really happy with the quantity as mine is not a massive fire, should last a good while.
