I've just bought the normal size dupont supreme and I'm really disappointed with it! Gardiners seem to have increased the vertical splay to a point that makes it pretty useless! 🤔
I used to use the flocked supreme and this was superb but this dupont one is terrible in comparison! Also, because of the size of the space required to fit jet capsules, there is at least 1" either side of the brush where there is only ONE row of bristles. On a brush which is smaller to begin with, this is a major oversight IMO and it really shows when you are cleaning a velux window and you can see light through the brush- there's two major spaces barely getting touched! This in turn means that even more movement is required to guarantee effective coverage from an already smaller brush! On a plus point, the dupont ultimate is very good but the blue nylon ultimate trumps them all. 🙂👍
