15sq foot shown on advertising picture while 20sq meters stated in written description. This is a Big Difference. Which is correct please?

It's extremely difficult to give an accurate answer on this as depends if the air is dead still or not. All I can say is that this bit of equipment has proved itself several times when battling with extremely aggressive Scottish midgies.

Can you refill the Butane Gas Cartridges?

Have seen someone on YouTube doing it but I wouldn't advise it..

How to use it? Does it stand in an area you sit in while camping? Or do you have to hold it?

We usually put it on our picnic table and that protects the area we sit. You don't need to hold it we lay it flat with the black grid facing up. We have tried using on the move and it doesn't work well like that but when in camp it works really well.

Can I use this inside a summerhouse, with the doors open?

The instructions (inside the box) state that the device should not be used in a confined space. It There is risk attached to using in a summerhouse even with the doors open. I would suggest asking the manufacturer for further guidance. I now use a plug in device from Jungle available from Amazon or currently on offer in Wilko.
