The price difference is justified by the additional freebies in the pack
I am a fan of the Silkepil line from Braun because I think it's the best one on the market yet and I have tried a few. I am not yet fully convinced of the significant price difference between this model with the flexible head and an older model. I have tried both at the same time and apart from less noise in the newer model, the results are the same. I am speaking about the epilator itself.
When talking about the facial brushes, there I see a significant improvement compared to older models. The drawback of that is that when people are out on the marked for an epilator, maybe they don't want to spend the extra money on facial brushes and stuff (I personally had a separate facial brush that I really like).
All in all a good product, but if you don't want to spend so much money on an epilator and you have an older model, you are not losing anything.
