I previously owned the Norelco QT-4021 trimmer but it is starting to loose it charge fairly quick. This model is similar but a lot nicer to use due to its slim design. Also, it is made for wet or dry use which makes it much more versatile. I am pleased with this new model and plan to buy another one in the future just for a back-up.
