I bought 100 pre cut from cleaning spot what a load of crap, you can't even turn them around as they get to knackered on the first side all the edging just wears away. Also they don't take all the soap off the windows, I used about 6 then thought I'm not having this so got onto cleaning spot and to be fair I'd had them for around 6 weeks as now it's more pole work than squeegee and they did given money back so I purchased the 12" unger pre cut black blades which are sooooo much better and you can turn them around.
