Although the Cuisipro Foam Pump is not perfect, it is significantly superior to other foaming soap dispensers that I have tried. I own several Cuisipro pumps, and I occasionally purchase an additional one for the house or for a gift. PROS: Good foam lather. The foam lather rinses easily off your hands (and off eye glasses), whereas non-foaming soap takes a bit of rinsing to get all of the soap off. Economical. The dilution is 1½ ounces of soap to 8 ounces of water. (Don't worry, you do not have to measure. There are fill lines on the back of the dispenser). If you prefer a lighter lather, or even greater economy, you can use an even higher dilution. The angled spout aims the soap slightly downward, so that if the tip were to clog (as other brands of dispensers do), it would not shoot straight out and cover you with soap. The spout extends far enough beyond the bottle so that it is over the sink, and so that it will not drip soap onto the outside of the dispenser. The spring is pretty dependable with proper cleaning (see CARE TIPS section, below). If the spring does become sluggish, the large plunger handle makes it easy and convenient to pull the plunger up to its full height. The suction cup keeps the dispenser in place. The inverted well that holds the suction cup, creates a "soap moat" inside of the soap container. This provides two benefits: (1) it provides additional accuracy when filling the liquid soap to the correct level, and (2) it allows the pump, whose suction tube is exactly long enough to touch the bottom of the "moat", to pump the soap completely to the last drop. Good ergonomics and styling. The sloped unit with wide plunger handle does not look like something that you bought at a supermarket. Very attractive with a drop of food coloring in the soap, or with already colored soap (such as Soft Soap's "Black Raspberry & Vanilla"). I would have preferred glass rather than plastic, but I accept the fact that plastic is a lot safer. This unit has a 25-year manufacturer's warrantee, and a 90-day Amazon.com warrantee. Keep your receipt and the warrantee info. Amazon.com provides a free UPS return label. According to another reviewer, the manufacturer replaced his unit without his having to mail the defective one back. CONS Any liquid soap dispenser (not just this one) will develop a sluggish spring return if soap gums up around the moving parts. This is a minimal problem with this dispenser if correctly cleaned (See CARE TIPS, below). If you do allow it to become sluggish, the pump handle will still spring up high enough to use, and the wide pump handle makes it easy to lift it all the way up. One of my pumps died and I had to return it (See warrantee information under "PROS", above). The pump mechanism appears to be held in place by a friction ring washer. If you disturb it while cleaning, it can come off, and the pump will never work again. See CARE TIPS, below, for how to clean the dispenser without disturbing the pump unit. Liquid soaps that are PRE-DILUTED and sold TO BE USED AS IS in foaming dispensers, may still need to be further diluted significantly, because of components that might gum the moving parts with residues. My favorite liquid soap that is pre-mixed for foaming dispensers is Young Living Thieves. This soap contains essential oils, and, through experimentation, I find that I need to further dilute it 1 part soap to 3 parts water. Clear or translucent Soft Soap refills, on the other hand, work perfectly when diluted per the Cuisipro instructions. I suspect that trying to use one of their creamy soaps would be deleterious. CARE TIPS Rinse and flush the pump with clear water between each filling. (Do not try to clean the lid or pump mechanism with a cloth. Doing so could dislodge the pump from the lid). Simply fill the dispenser ¼ full with clear water. Shake it. Then replace the lid. You can continue to use the dispenser as long as lather comes out. When the lather becomes thin. Then repeat the process a couple of times, rinsing the dispenser, filling ¼ full with clear water, replacing the lid and shaking, and flushing the pump by pumping clear water through it. This will flush out any soap residue that might be starting to accumulate. (You can also use a bottle brush on the bottle if you like - just not on the pump or lid). Then empty the dispenser and fill it with liquid soap and water, per the Cuisipro instructions.
