Embodiments include a dispenser for dispensing a product. The dispenser has a housing, a container, a container holder and a first holder magnetic element positioned on the container holder. The first holder magnetic element and a first stationary magnetic element interact to create a first magnetic force. The first magnetic force can induce the container holder to move. The position of the container holder along an axis of the container holder is correlated with the weight of the product remaining in the container. An indicator may alert user regarding the amount of product remaining in the container based on the position of the container holder.
