I ordered this soap pump when simplehuman had a sale due to the pandemic. I thought it was larger than this but when it came I was pleasantly surprised to discover that it fit its location on my kitchen sink perfectly. It's small enough to be unobtrusive, but large enough to hold just enough liquid soap to last for weeks. I love the quick shot of soap it releases which isn't wasteful at all. It's my first sensor pump but it won't be my last. Love it!
