    {"id": "demo-003", "source": "reddit", "context": "r/dogs · 帖子评论(虚构)", "votes": 98, "text": "Bought one of those reusable rollers everyone recommends. The handle snapped in two weeks. Cheap plastic, total waste of money."},
    {"id": "demo-004", "source": "reddit", "context": "r/dogs · 帖子正文(虚构)", "votes": 87, "text": "Why is there no tool that actually gets dog hair out of car seats? I've tried a vacuum, tape, gloves... the hair is woven INTO the fabric. So frustrated."},
    {"id": "demo-005", "source": "reddit", "context": "r/CatAdvice · 帖子评论(虚构)", "votes": 76, "text": "My cat sleeps on my black work clothes. The sticky rollers leave a residue on wool and I'm scared they'll pull threads on my sweaters."},
    {"id": "demo-006", "source": "reddit", "context": "r/CatAdvice · 帖子评论(虚构)", "votes": 71, "text": "Honestly the self-cleaning base is the only reason I'd upgrade. Emptying the fur chamber by hand is gross, the hair sticks to my fingers and floats everywhere."},
    {"id": "demo-007", "source": "reddit", "context": "r/HomeImprovement · 帖子评论(虚构)", "votes": 64, "text": "Every 'pet hair remover' I bought works for the demo video and then does nothing on real embedded hair in the carpet. No difference after ten passes."},
    {"id": "demo-008", "source": "reddit", "context": "r/CleaningTips · 帖子评论(虚构)", "votes": 58, "text": "Pro tip: slightly damp rubber gloves. Free and works better than the $25 gadget I regret buying."},
    {"id": "demo-009", "source": "reddit", "context": "r/dogs · 帖子评论(虚构)", "votes": 52, "text": "The one I got scratched my leather car seats. Now I have fur AND scratches. Terrible design, the edge is way too hard."},
    {"id": "demo-010", "source": "reddit", "context": "r/CatAdvice · 帖子评论(虚构)", "votes": 44, "text": "I need something for stairs. Carpeted stairs are impossible, the big roller doesn't fit into the corners at all."},
    {"id": "demo-011", "source": "reddit", "context": "r/CleaningTips · 帖子评论(虚构)", "votes": 41, "text": "Laundry is my problem. Hair survives the washer AND the dryer. My scrubs come out with more cat hair than they went in with, I swear."},
    {"id": "demo-012", "source": "reddit", "context": "r/dogs · 帖子评论(虚构)", "votes": 39, "text": "Anything battery powered dies in a month. My handheld fur vacuum stopped working after like 12 uses and the brand ghosted my warranty email."},
    {"id": "demo-013", "source": "reddit", "context": "r/CleaningTips · 帖子评论(虚构)", "votes": 33, "text": "The refill sheets cost more than the roller. It adds up to like $80 a year just to keep my couch presentable. There has to be a reusable option that actually works."},
    {"id": "demo-014", "source": "reddit", "context": "r/CatAdvice · 帖子评论(虚构)", "votes": 29, "text": "Velvet couch owners, beware: the 'fur magic' brush snagged the fabric and left a shiny track mark. Ruined the seat cushion."},
    {"id": "demo-015", "source": "reddit", "context": "r/HomeImprovement · 帖子评论(虚构)", "votes": 24, "text": "I just want one tool that does couch, car and bedding. I own five different removers and none of them does all three well."},
    {"id": "demo-016", "source": "reddit", "context": "r/dogs · 帖子评论(虚构)", "votes": 21, "text": "Husky owner here. Shedding season means I clean the couch twice a day. Whatever tool it is, it needs to be FAST, I don't have an hour."},
    {"id": "demo-017", "source": "reddit", "context": "r/CleaningTips · 帖子评论(虚构)", "votes": 18, "text": "Does anyone make one with a longer handle? Bending over the carpet for 40 minutes kills my back."},

    {"id": "demo-106", "source": "amazon", "context": "1★ 差评 · 除毛手套(ASIN 虚构)", "votes": 41, "text": "The hair just sticks to the glove and then you can't get it OFF the glove. You end up picking fur off with your other hand. What's the point?"},
    {"id": "demo-107", "source": "amazon", "context": "2★ 差评 · 宠物毛发滚刷(ASIN 虚构)", "votes": 38, "text": "Left sticky residue stripes on my linen couch. Now dust sticks to the residue. It's worse than the hair was."},

    {"id": "demo-109", "source": "amazon", "context": "2★ 差评 · 宠物毛发滚刷(ASIN 虚构)", "votes": 30, "text": "Too big for car seats and door pockets. Fine on a flat sofa cushion, useless in any corner or seam where the hair actually collects."},

    {"id": "demo-111", "source": "amazon", "context": "2★ 差评 · 宠物毛发滚刷(ASIN 虚构)", "votes": 26, "text": "Replacement heads are $12 each and you need a new one every month with two shepherds. The cheap upfront price is a trap, the refills are the business model."},
    {"id": "demo-112", "source": "amazon", "context": "1★ 差评 · 手持除毛吸尘器(ASIN 虚构)", "votes": 25, "text": "Stopped charging after 6 weeks, just outside the return window of course. Support offered me a 15% coupon. Never again with this brand."},
