What every best has:
We found the most exhaustive tests of the Go Duster at KFVS (Cape Girardeau, Mo.), which also publishes a video of the testing process. The Go Duster is also tested at KCBD (Lubbock, Tex.) and by an editor at the Pittsburgh Post-Gazette. EZineArticles.com and CravingTech.com each offer a critical review based on hands-on testing. We found the most owner-written reviews and ratings at Amazon.com. There are two brief reviews at Buzzillions.com, but they lack detail.
A viewer named Mary tests the Go Duster on pieces of furniture throughout her house, giving it a grade of F because it not only doesn't polish wood, it just spreads dust around. When it's tested on window blinds, it just closes them shut instead of cleaning them. After observing the testing, reporter Lauren Keith concludes by saying, "I wouldn't even use this like a light feather duster either. A rag or a feather duster is cheaper and would work better for that." A 3.5-minute video accompanies this article, showing the tests and their results.
The reviewer here is enthusiastic about the Go Duster and concludes that it works very well. After trying it on a variety of items, including blinds and a fan, she is very impressed. She doesn't seem to mind that it causes dust to fly everywhere -- including all over herself. In fact, she thinks the whirling dust is a testament to the Go Duster's cleaning power.
Home editor Kevin Kirkland and his family test the Go Duster in their house. They give it a positive review because it's fast and fun and dusts fragile objects well. The only drawback noted is that the "lifetime" supply of cleaning spray actually gets used up fast.
Reviewer Lee John notes some drawbacks that he encounters when using the Go Duster: He has to keep a thumb on the switch the whole time the Go Duster is being used, which is a strain on the hand and wrist. He warns to be careful when using it on ceiling fans and dangling objects, because the fast-spinning brush bristles could easily get stuck. Based on the amount of dust that's generated, John says this device is not ideal for allergy sufferers. Despite these warnings, he says the Go Duster works great at cleaning blinds, slats and other hard-to-reach areas.
After testing the Go Duster, this reviewer concludes that it's worth more as a toy than as a dusting tool, since it flings dust all around (and can aggravate allergies). A video here shows the Go Duster being used to pet a cat.
Of the 20 or so owners that review the Go Duster here, a little over half are pleased with it, saying it works as advertised. However, nearly as many owners give it extremely low ratings, complaining that it just spreads dust around, that parts of the brush itself fly off, and in some cases, that it's so poorly made that it either doesn't rotate or spins oddly.
The two very brief reviews here, originally published at Walgreens.com, are enthusiastic but lacking in detail.
