I've been using the SetSail Blind Duster for a few months now, and it's been a mixed experience. The concept is brilliant - cleaning blinds without taking them down is a game-changer. The three-armed design lets you dust multiple slats at once, and the microfiber sleeves do pick up dust effectively.
On the positive side, I love how lightweight and easy to handle this tool is. The included spare microfiber sleeves are convenient when one gets dirty (which happens quickly). Washing them in a mesh bag (like for delicates) keeps them in good shape - they survived multiple washes this way.
The tool works best for light dusting. When I first used it on my wooden blinds, I was amazed at how much dust came off. It's also versatile - I've used it on air vents and ceiling fan blades with decent results.
However, there are some issues. The microfiber sleeves tend to slide up during use, requiring constant adjustment. More concerning is the durability - while mine hasn't broken yet, I'm careful not to squeeze too hard after reading other reviews about broken arms.
The biggest drawback is the customer service situation. Multiple users report invalid contact information, which makes me nervous about potential future issues.
For occasional light cleaning, this duster works well enough. But if you have heavily soiled blinds or need frequent deep cleaning, you might want something sturdier or consider professional cleaning services instead.
