Um...yeah, because hand cleaning the toilet, then hand applying sticky plastic, then using your hands to plunge the thin plastic sheet (hoping it doesn't break or loose it's seal or you fall in), then removing a crap covered plastic sheet and disposing of it somewhere is SO much better than just using a normal plunger...ingenious Korea!

Yes, it is way better.
1). First, that toilet isn't going to spill over. Ever had that happen? And with a heat register near by? Disgusting.
2). Two, do you realize how much Feces is splashed around the bathroom when you plunge? Not just on your floor, but walls, and on you, your clothes and possibly your face. It's not just the big drops, but the little ones, the ones that practically become airborne.
3). Three, Clean up afterwards, once you're done with a plunger, you need to clean it off, and if there is stuff sticking to it, as you can guess, that's not fun either. Not to mention, where are you going to clean it? in the bathtub? After you sanitize the plunger, now you have to sanitize the tub, or sink, or what ever as well.

-You're going to need to wipe down that toilet whether you plunge or use this sheet.
-This plastic sheet, looks strong enough that it's not going to break.
-And disposing it. Well, lifting it into a garbage bag, that just seems way easier.

OK, I see your points but....
1)with the plunger right there in it's holder, I never let it get close to spilling over, what a mess that would be (and there is a heat vent right there, UGH!)

2)I try to be careful plunging and not splash at all, but you do have a good point here, it would be cleaner, especially for those that get crazy plunging.

3)I leave the plunger in the toilet and flush again (at least once), to rinse it off some before removing it at all, then place it in it's holder. Granted, that's a bit nasty, but it never smells, and I give it a spray of bleach too. Every so often, while it's dry, I take it outside and wash it in the yard where the sun will sterilize everything.

The plastic seems to require you to clean before AND after, by hand at first BEFORE you can plunge (edit: with your face right next to the clog!)...and that's impossible if it's overflowing! Then what?!? A plunger can be cleaned up after at your leisure (better be before the wife needs the toilet though) and with scrubbing bubbles and/or bleach if that's your preference.

It may be strong enough to survive 'plunging' with your hands, but I certainly don't want to be the one to test that, or to find out it wasn't! It looks like if you don't get a perfect seal (so a perfect dry and clean rim first) it could easily detach. UGH!

Disposing the plastic requires you to take it to the garbage bag (or the bag to it) and then to take out that bag, which may or may not mean dripping it through your home, depending on your bathroom garbage. (mine has no bag)

All that said it's an interesting idea, but I think I prefer the plastic plunger. To each his own though.

All I can imagine is applying slightly too much pressure, or not having the perfect seal and ending up, both arms, elbow deep in fecal soup; Creating a lovely splash coating my surroundings, face, and upper torso. No thanks.

Won't work in my toilet. The pressure would just go up the water tank. Our water comes from the top, not from the bottom.

This is so stupid on too many levels to list. Waste, laziness, whatever. Great example of a seemingly great product marketed well, and nothing more.

I think you all need more fiber.

Prevention is always the answer!

But I see a couple of issues with this method:
1) It's cheaper to buy a plunger once that you can reuse vs these one-time use stickers.

2) at least in US there's are no standards for toilet bowl shape.
There are a couple of common types, but otherwise it's a wild west.

3) from physics point of view plunger is better. You are applying force to a smaller area. With this cover you are spreading it out over the whole bowl opening. Youtube has videos of ppl being unable to push down on that film..

Aint no way. If that thing had any kind of defect it'd turn into a pressure filled sprayer. While cleaning the floor sucks when it runs over, cleaning the ceiling and walls would be worse.

I do however wish we'd get over the low flow requirement for toilets.

Genius. It could only be better if you could then roll up that thing and flush it when you're done.

Not just good marketing. A very useful product that I would love to be able to purchase.

Fast forward to 2:49... Nuff said.

Everyone else seemed to miss the point that this can't be used if the toilet is already overflowing even barely...not at all. Kind of defeats the purpose when it's needed most.

*engineering - clever stuff!

Adding video to channels (Engineering) - requested by Zawash.

I've seen people doing that in Brazil many years ago. Difference is that they use cardboard, flush the toilet and stand on top of it. It's a messy business. Shit everywhere. But it works.

We need more data on usage. I hope it works! Hate plungers.
