Works perfectly. It’s a little too easy to trigger by accident, though. It kept spraying soap all over the sink rim. So, I just keep it turned off until I want to use it.
This is my fourth liquid sensor pump soap dispenser. I really like the way the product works and looks and I have them at all my sinks. I don't like that I have had to literally throw away two others that stopped working and which Simplehuman did not stand behind either to fix or to provide a decent way of disposing of them. I will still use them, but with caution.
There is no middle ground. You either get a little drop (so you have to go 3-4 times to get enough) or you get twice as much as you need. I experimented at different levels, but there is no in-between. I prefer when you can set the amount. I'll deal with the batteries it's worth it.
