Just refilled 7 cartridges with butane. Should get me a week or ten days into the season I hope. Still have to recharge the permethrin pads. It'll be here before you know it fellas!
Yes, supposedly. This was my first time refilling the fuel cartridges. Supposedly you mix a small amount and put it in a small dropper bottle. Put a few drops on the old inserts and let it dry and you're ready to go.
