Niagara 77001WHCO1 Stealth 0.8 GPF Elongated Two Piece Toilet, White

Niagara's innovative and stylish Stealth Ultra-High-Efficiency Toilet goes a step beyond standard water-saving toilets with a 0.8 gallon per flush (GPF) flush rate. By harnessing the energy of water filling the tank, Stealth uses a patented air transfer system to pressurize the bowl's trapway. Once activated by pressing the flush button, the swift, powerful and quiet flush evacuates all waste in the bowl, using just 0.8 (3 liters) of water. Offered in both round-front and elongated bowl models, and adaptable to fit a 12'' rough-in installation, Stealth easily replaces existing toilets, lowering water usage and utility bills like no toilet ever has!

5/5 Starsbest toilet ever | I have owned a Niagara Stealth for over 6 months and installed it in our downstairs powder room. Simply put, after much research online and in plumbing stores, I found the best toilet I have ever seen and am about to buy enough for every bathroom in my home. This toilet just does not clog with half the water usage of my old toilet and is remarkably quiet to boot. Look no further. This is the best toilet ever.
Recommended? Yes.
5/5 StarsGreat product | I researched a lot of products before I purchased this. For price and water conservation (lower bills) this looked like the best option. I was a bit hesitant because I just could not see that 0.8 gallons of water would be sufficient. I'm ever so glad I ordered this. The flush is quiet and oh so efficient. One flush and gone. If you need more water the flush button can be held longer causing the rest of the tank to empty. I'm pleased enough that I ordered 2 more to replace the others in the house
Recommended? Yes.
4/5 Starsvery good performer | I have had great success with this toilet. I have purchased two of them to reduce water and sewer expenses and was surprised to find how well it performs.(see below for details of my experience)
One in my home I have been using for nearly a year and one I purchased a month ago for my job at an office trailer that flushes to a holding tank requiring regular pump outs. The second one will have paid for itself in another month. Nobody at the office was aware that the new toilet was an ultra high efficiency toilet until I told them after several weeks of use when discussing what to do with the old one.
It works very well, is very quiet and the bowl keeps itself very clean.
It does Occasionally require a second flush when clearing solids to get some stray particles remaining visible in the water. A second flush can be done immediately without waiting when it is required. I would say this happens about every tenth flush of solids on average and never happens when flushing liquids. It has plugged on me one or two times in the last 10 months. (about the same rate as the kohler it replaced) This toilet does not sweat since the tank holds several gallons that temper the incoming 0.8 gallons of water. I like the High seat height as well, it is much more comfortable. The toilets that were replaced were an 8 year old Kohler Welworth 1.6gal/flush in my home and a 10 month old 1.6gal/flush no name toilet at work.
I would say it flushes as well as the Kohler wellworth and much better than the no name toilet. Overall I would rate it better than the kohler since it does not sweat and in the unusual event that a second flush is required you do not need to wait for it to refill the tank. It probably requires less cleaning than the wellworth and the no name.
I highly recommend this product.

* additional note As far as the volume of water used goes, the 0.8 gallons is a real number. When I purchased the first toilet I could not believe how well it flushed and did not believe it could be such a small amount of water so I measured it out for several flush cycles. Each time it required 3/4 of a gallon to fill the tank back to the line each time. Having said that the water usage is somewhat adjustable. So you can dial it back or increase the volume if you like to tinker.
After tinkering I set Mine back to the the factory setting.
Another note, the fill valve is a standard fill valve that can be purchased at any hardware store. The flush valve, I am pretty sure, is unique to this toilet. The two flush and fill valves are the only moving/wear parts on the toilet, not much different than a standard toilet.
Recommended? Yes.
