### ⭐⭐⭐⭐⭐ Review
*by I***E on 16 January 2025*

It is exactly as depicted. The plastic is fairly thick for what it is, so considering its placement I think it will last a very very long time. The one we had prior was entirely made of rubber and it had sagged and torn over time, leaving an endless flow of water that racked up an extra $50/m on our city bill. Putting this on was SUPER easy, I am a woman (and certainly not a plumber) and I had no problem clicking it into place or attaching the chain to the lever. I love the price, very fair. As mentioned, the top cap is plastic, but I find that beneficial. Firstly, it will not sag as the old one did. Secondly, it makes movement easy, as its quick to lift and quick to drop. Mind you this toilet is in my young children's room, so they need something that doesnt require excess effort to flush. Highly recommend.
