I purchased two soap dispensers and one foam dispenser the one soap dispenser stopped working and I took it apart put it back together and it worked again for two days then it stopped again I called the company they had me reset it I reset it it stopped working they replace the unit the new replacement units doing the same thing just puts out a little bit I reset it I’ve done everything .the foam dispenser seems to work best have not had a problem with it so far. It’s also rechargeable so you don’t have to change the batteries theI second soap dispenser now it’s starting to do the same thing give me a problem with the amount of flow I would definitely recommend the foam dispensers over the soap dispenser is way too much problem for the amount of money
