I am always surprised at how small the resupply for You-cleaner. A double thimble, nothing more. The You-Glass Cleaner is made of the whole series is my absolute favorite. Power windows and other smooth surfaces super clean, smells only slightly flowery and functions without any alcohol. Refilling is very simple: unscrew the spray head of the bottle, the resupply it screws up to crack down on the bottle, let the concentrate run into the bottle, unscrew the cap, top up with water in the bottle, and screw on the spray head again. Shake briefly, that's it. From value for money here, there is nothing better in my eyes. From me why there's a definite recommendation.
