I have seen these quite a lot on YouTube and Facebook, but never seen them for sale in the UK before a blight imported from the Ukraine, has any one used one, what are folks thoughts on it?

The appeal to me over to say something like the gas vap or sublimox is the multi colony treatment load.

Chris, they don't actually vaporise the oxalic acid as it's in an ethanol solution. It's the micro crystals formed when your sublimated oxalic s condenses in the hive after vaping that cause the damage. They don't seem to work very despite all the video. Check Randy Oliver's varroa control pages, he does not recommend them for control of varroa.
Worth remembering that when you dribble oxalic acid it is only effective if sucrose is present.
