Not a good product.
It required more work to use these than if I just got a rag and did it the old-fashioned way. The Three prong cleaner is very difficult to hold closed while you clean the blinds. After the first full blind my hand and thumb were cramping so bad I had to stop.  There is quite a bit of tension required to hold them close with enough pressure to actually get any dirt and dust off of them. The microfiber sleeves  don't provide enough of a textured surface  give you any scrubbing action whatsoever. I live in an area where pollen collects on the blinds and can be a chore to get off. If I tried to use this product to clean my blinds I think I would still be doing the job. Do yourself a favor, and get a wet rag with some mild soap and do it the old-fashioned way.  Additionally, trying to work around the strings was very hard using this product and much easier if you just use a rag and your own two hands.  It's faster.
