Such a great piece of kit, takes no more space and it works for me incredibly well. I would normally change a blade every 2 weeks or so, I am into my 7th week with my current blade and it is still doing a great job.
I have bought 3 as gifts now, Not the biggest money saver of all time but one that works with no real extra effort. Mine will pay for itself this year for sure. I have been using it 3 months now. Great success.
