There is no +/- to adjust the amount of soap dispensed. We have to put our hands under the sensor multiple times to get enough soap. Sadly, we can’t use this.
The two questions every user will have are: 1. ) How much soap is remaining in the reservoir. 2. ) How much battery charge is left? This canister's new metal design - and the product - ignore customers' questions. I purchased the prior design for almost every member of my extended family, about twenty of the older and excellent product.
The color of this is very nice. However, unlock my other soap dispenser I have from here, there is no light to indicate whether this is charged or out of soap.
