This product has been improved in turns of its weight as compared to the old one that I had. I have not yet found any shortcomings so far. If there is, it would be great that it is accompanied with a stand that holds the razor as the old one.
The only thing which be improved is the the battery charge indication. I never really know when it's ready to be charged again so I charge it rather frequently. I'm afraid that I may be shortening its life by overcharging it.
