My double glazing unit is now moisture free! a great idea and hack.

Took my time drilling the holes, and kept dipping the point of the drill bit in water. No problems I applied the vacuum cleaner to one hole, to pull dry warm air through the unit, and must have created a perfect seal. That created a partial vacuum

I bought the 3 x window kit easy to follow instructions the moisture cleared up in a few days I would recommend for cheap alternative to paying to have them replaced

Many thanks Item arrived well packed and on time. Not tried it yet but hopefully will work well
