There is a reason this product has a list price of 229 and can be bought for 139. It isn't good. Mine has lasted a total of 6 months before becoming plagued with issues and problems. Also, the convex cutting system will probably NOT catch on. It isn't superior to Panasonic's old system at all and seems to be more problem plagued. I bought a Pro Curve Linear Pivot. Much cheaper at 80 bucks and let me still you...it doesn't look as nice and feels a bit cheaper but it operates much better and actually gives a better shave. I really really hope Panasonic is planning on phasing the old shavers out and replacing them all with these "well-intentioned" but faulty and disappointing convex systems. Also, the one piece design of the shaver foil isn't great either. I had a previous Panasonic with this design and it also disappointed.
