TOTO Aquia IV One-Piece Elongated Dual Flush 1.28 and 0.9 GPF WASHLET+ and Auto Flush Ready Toilet with CEFIONTECT, Cotton White, Vitreous China, CST646CEMFGNAT40#01

The TOTO T40 Aquia IV One-Piece Elongated Dual Flush 1.28 and 0.9 GPF Universal Height WASHLET+ and Auto Flush Ready Toilet with CEFIONTECT is the epitome of modern form and function. The skirted design conceals the trapway, which enhances the elegant look of the toilet and adds an additional level of sophistication. The one-piece design is not only aesthetically pleasing, but also offers the benefit of being easier to clean versus a two-piece toilet. By removing the gap between the tank and bowl, we eliminate the hiding place for dirt and debris. An additional benefit of the one-piece toilet is that there is no threat of leaks from bolts or gaskets that can occur in two-piece toilets. The Aquia IV features TOTOs DYNAMAX TORNADO FLUSH, utilizing a 360 degree cleaning power to reach every part of the bowl. This version of the Aquia IV includes CEFIONTECT technology, a layer of ceramic glaze that minimizes waste from sticking to ceramic surfaces. This feature, coupled with DYNAMAX TORNADO FLUSH, helps to reduce the frequency of toilet cleanings, minimizing the usage of water, harsh chemicals, and time required for cleaning. The enhanced design of the Aquia IV inner bowl reduces water flow resistance and turbulence, resulting in a quieter flush. The chrome center-mounted push button that sits atop the tank allows you to proactively conserve water by choosing between a 0.9 GPF rinse or 1.28 GPF for tougher jobs. This version of the Aquia IV offers TOTO T40 WASHLET+ and Auto Flush compatibility for when you are ready to upgrade. WASHLET+ toilets feature a channel on the bowl surface to help conceal your WASHLET+ supply line and power cord for seamless integration. The Universal Height design allows for a more comfortable seat position across a wide range of users. The TOTO Aquia IV meets the standards for EPA WaterSense, and Californias CEC and CALGreen requirements. The Aquia IV comes ready for install into a 12" rough-in, but may be adapted for a 10" or 14" rough-in with the purchase of a separately sold adapter. Does not include seat or WASHLET. Additional items needed for installation and use must be purchased separately: compatible WASHLET or seat, wax ring, toilet mounting bolts, and water supply lines.

Broke Within Moments
My two medium sized dogs played tug of war ONE time and it ripped in half. Not durable at all. Did not hold up well.

My dogs love fetching this toy, then fighting over who’s going to bring it back to me
Both of my miniature dachshunds took to this tug of war toy immediately after opening it. I liked the fact it didn’t smell terrible like most of the scented dog toys I’ve purchased in the past. Instead this one actually smells good, it’s sweet and fruity smelling. It’s extremely durable and very heavy duty. The only problem is that it’s pretty thick and heavy, especially for my small dogs. They still like playing fetch with it, then fighting over which one gets to bring it back to me. It really would have been the perfect fetching toy for them, if only it had been a little bit smaller and lighter. If you have larger sized dogs who enjoy playing fetch and tug a war, I’d recommend giving it a try.

Good Quality Toy, but Not a Hit with My Dogs
I am a bit unsure about this toy. Unfortunately, my dogs do not seem to enjoy it very much. I thought the blueberry apple scent would make it more appealing, but they tend to lose interest almost as quickly as they start playing with it. I was hoping this would be something we could use for games like tug of war, but it just has not held their attention. That said, I may just have picky dogs, so this could be a different experience for others. The reason I gave it two stars instead of one is because the quality is actually quite nice. It feels well made and has a good overall design. However, I would be a little cautious giving it to aggressive chewers, as it seems a bit on the softer side. For dogs that are more gentle with their toys, it would likely be a better fit. The size is also great, and it has a lot of potential. It just has not gotten much use in our house, likely due to my dogs not being fans of the flavor. Overall, if you have picky pups like mine, this may not be the best choice. But for less selective or gentler dogs, it could still be a solid option

Stretchy, but Smaller & Softer Than Expected; Berry Fragrance Dominates; May be Best 4 Puppies
I was directed to read guidelines that were on the internet, prior to use. I was not expecting that and that was a big turn-off. Basically, it's all about liability, this product has the possibility of being torn apart and I am basically warned that if a piece is chewed off, that's bigger than a grain of rice, to toss, this. I was repeatedly reminded, again and again, and again that pet safety was my responsibility. Yeah, I know that. All these suggestions and warnings should have been made clearer in the listing. Is this built to flex? Yes. Does it bend? Yes. Does it stretch? Yes. Is this rugged? That's open to debate, based on the users, for a puppy, to some degree, but their teeth are very sharp. Is this soft on teeth? I don't disagree. Does this have a durable design? Depends on the user. Floats in water? I do not doubt it. Does this have an enticing scent? For a human, yes, for a pet? Depends if your pet loves berries. This is no pigs ear/bone, so, chewing is not a natural draw that I saw, which I think may be better, because this is soft and easier to tear to pieces than expected. To motivate the first time, I found it best to initiate the tug of war, but this is smaller than I envisioned too, causing me to have to bend considerably to participate. A tennis ball in a tube sock is longer. A two-dog tug of war works best with this. Nevertheless, it's a better toy than teaching pooch to have a battle using clothing, avoiding future attractions to my socks. There is some flexibility to this. Durability is an issue. I think this would have been more interesting if it had been made out of rawhide. It does have a comfortable grip, for a human, but the toy pays a price for that with what I would consider fragility. The berry fragrance dominates, it's nice for a human, but sorry, it ain't no bacon aroma. It's like a thick heavy rubber hose. Value? In hindsight, I just do not see the value I was expecting. I mean really, a grain of rice warning not to use. Durability at issue in my eyes. Country of origin? Vietnam. Is this perfect? Not in my opinion. Rating? A strong three (3) stars at best in my eyes. This is not for a tough chewer. I have to constantly monitor its condition. It does succeed as a tug toy, but it has more limitations that I was expecting. I hope my thoughts added a bit of information.
