"Shower was basically a bath by the end of every wash lol. ankle deep water every time. dropped one in, left it overnight, shower drains like its brand new"

"Those little drain flies around the kitchen sink are GONE. I didn't even buy it for that, I bought it for the smell, but the flies packed up within the week."

"Tried the liquid stuff for years. It'd clear for a week then slow again because it never got the gunk off the pipe walls. This actually dissolved the black sludge. Water runs FAST now."

"Rental landlord here. I drop one of these in every turnover now, kitchens and bathrooms. Cheaper than one call-out and the drains are fresh for new tenants."

"Good stuff, does exactly what it says. Only thing is I wish the pack came with a couple more blocks, we have 3 bathrooms and went through them fast."

"my flatmate has the longest hair known to science and our shower drain was basically a hairnet factory. one block. ONE. sorted"

"Bought the 3-pack and did every drain in the house in one night. Kitchen, both bathrooms, laundry tub. Whole house just smells... neutral now. Forgot what that was like."

"I was skeptical because nothing else worked, not the snake, not the plunger, not the crystals. Woke up, ran the shower, and watched the water spiral down like a commercial."

"Kitchen sink would fill up washing one pan. ONE PAN. Now I can run the disposal and the water just leaves. Should have bought this a year ago."

"Cleared our slow tub drain nicely. Took longer than I expected, put it in at night and by the second morning it was flowing properly. Patience required but it works."

"We run a small Airbnb and guests kept mentioning a 'musty smell' near the kitchen sink in reviews. Two blocks later the smell is gone and so is that feedback."

"Dropped one in the shower Sunday night. Monday the water wasn't pooling around my feet for the first time since we moved in. That's it. That's the review."

"It works but our kitchen clog was bad enough to need two blocks over two nights, and shipping took a while to get here. End result is a clear drain though."

"grease. so much grease. we cook a lot and the kitchen drain was basically lined with it. water used to sit there swirling forever, now it drops straight down"

"Used it in the guest bathroom before family visited because the sink smell was embarrassing. By the weekend nobody could tell. Crisis averted."

"Does the job. Bathroom sink and shower both flowing again. I'd say give it the full night like the instructions say, I rushed the flush on the first one and it only half worked."

"I'm on a septic system so I'm careful what goes down the drains. Used these for two months now, drains are clear and zero issues with the tank. Happy days."

"Soap scum ring around the shower drain, water sitting grey on top of it every morning. one block later the whole thing just rinses clean. so satisfying"

"I clean houses for a living and I've started recommending these to clients with smelly kitchen sinks. The drain fly thing alone makes it worth it, they vanish."

"College rental, four guys, one shower. I'll spare you the details. The drain runs clear now and the bathroom no longer has a smell I can't describe in polite company."

"Kitchen sink was gurgling every time the dishwasher ran, like it was struggling. Dropped a block in, next cycle total silence and the water flies out."

"wife's hair + my beard trimmings had built some kind of concrete in the bathroom sink. fizzed away overnight. genuinely impressed"

"Moved into a new place and the shower drain smelled like old water and regret. Previous tenants clearly never cleaned it. Two nights with these and it's like a hotel bathroom now."

"The slow drain in our laundry sink backed up every time we washed the dog. Not anymore. Simple as dropping it in and walking away, my favourite kind of home repair."

"I've spent more on liquid drain cleaner this year than this pack costs and none of it lasted. Three weeks since I used one block and the sink is still draining instantly."

"Good product. Bathroom drains are perfect, kitchen took two goes because of grease buildup, which is fair enough given what we cook. Ordering the bigger pack next time."

"Those tiny flies were breeding somewhere in the kitchen drain and driving me insane for months. Used one block, then another a week later. Haven't seen a single fly since."

"Dropped it in before a work trip so it sat for 3 days. Came home, flushed it, and the shower drain swallowed water like a drain in a TV ad. 10/10 lazy maintenance."

"My bathroom sink filled up just from brushing my teeth. Minty water sitting there every morning. Not anymore, it empties faster than I can rinse the brush."

"Decent. Cleared the slow shower drain but the kitchen one is still sluggish after one block, probably needs another. Shipping also took longer than I hoped. Giving it a fair 3."

"Airbnb host, 2 properties. I put one down each kitchen and bathroom drain between longer stays. No more smell complaints in the reviews, which is the whole game."

"The water in the tub used to take ten full minutes to disappear after a bath. timed it. Now it's gone before I've finished drying off. Sorcery."

"Black slime came up out of the overflow hole while it worked which was revolting but also proof. Sink drains like it's brand new and the smell went with the slime."

"Honestly impressed. Only reason for 4 stars is the blocks are smaller than I pictured, but they punch above their weight. Two bathrooms and a kitchen all clear."

"Condo HOA has strict rules about what you can put down the pipes and charges YOU for plumbing call-outs. These are on the approved list and my sink drains perfectly. Winning on both fronts."

"My husband fishes every weekend and cleans his catch in the utility sink. The bait smell coming up from that drain was criminal. Gone. Completely gone in one treatment."

"Gran's house, kitchen sink older than me. She refused a plumber because last time they 'made a mess'. Did this while she was at church. She thinks the drain fixed itself and honestly I'll let her."

"Solid product. Shower and tub cleared beautifully. The kitchen sink improved a lot but still slightly slow, suspect there's something further down the pipe. Would still recommend."

"My wife's extensions shed like a husky in summer and our ensuite drain was basically felted shut. This dissolved what two different liquid brands and a drain snake couldn't shift."
