Got this about two months ago for cat hair on furniture and it works beautifully, no batteries or electronics to break and super easy to clean. After going through several lint/ hair rollers and other pet hair removal gadgets, I continue to be amazed as to how well this thing works–way better than any other method I’ve tried and also so much easier. Within seconds, all the white cat hair is gone from the couch. I tried it on the carpet too, and it’s unreal how much hair it will pick up. This is one of those rare products, which is relatively inexpensive (compared to multiple lint rollers), sturdy, simple, and incredibly effective. The only thing it won’t work on as well is clothing-save your lint rollers for that.
