I wanted to try a dual flush, but wanted the lever style (more accessible design than top push buttons, for kids or mobility restriction), so this was one of only a few options. Packed well (no messy styrofoam) and truly ready to put on the bowl. I ordered the matching bowl, but found the mounting dimensions (3 bolts that form an equilateral triangle) to be somewhat standard. Honestly, the tank is prettier than the matching Kohler bowl, but the limited water used in flushing might make this bowl design necessary for an effective flush. This tank is serious business and looks like a machine inside, but it works well and I feel better knowing we are wasting less water. I would compare this tank to a German car; well-made and reliable, but comparatively complicated/expensive to service or repair. The tank is smaller than our old 1.6 gallon tank and the mounting gaskets are more substantial and stable. Especially great for our small bathroom!

we feel better knowing we are doing our part to save water! works just like you think it should.
