For something as simple as a soap dispenser you wouldn't think you would have to do research before purchasing. Bought this new to go along with a new stainless faucet that was replacing the old chrome one. The one it replaced was a cheap chrome unit that had been working perfectly for 7 years. This piece of garbage did not work right out of the box. I then did some research and found the bulk of purchasers have the same issue I do. It takes 15 pumps to prime and dispense dish soap. After sitting an hour you have to prime it 15 times again. From what other purchasers have said, it won't be long until it will not work at all. Apparently if it works long enough I will be rewarded with the neck of the bottle breaking off and having the soap dump under the sink. Research this on Lowes or Home Depot and read the reviews. Do not buy it under any circumstances.
