Hi all,<br><br>I too, have a Windmill Delta, and you are quite right. The Windmill lighter is not WATERPROOF, nor does it make claims that it is. This is what they say and I quote: <br>"Water Resistant Rubber O-Ring Seals<br>Windmill Stormproof lights have five rubber O-ring seals to ensure water resistance and keep water out when the lighter cap is closed. "<br><br>Now, what this means is that it will still light in a storm ie. in rainy conditions. It is not like a watch which is WATERPROOF. The terms water resistant and water proof are totally different in meaning. These lighters are indeed water RESISTANT and not water PROOF. The same goes for watches. Scuba watches are waterproof to a specified depth. Some watches are only water resistant.<br><br>Unfortunately there is no lighter which is a Scuba Lighter...LOL. I do not believe they intended the Windmill lighters to be fully submerged in water for any length of time.<br><br>I still think it is a great tool if used the way it was intended.<br><br>Cheers.
