But tibit, they didn't engineer it that way; did they?
They didn't improve the circuit and offer it as a paid or free upgrade. They sold the fancy-looking handle and let us pay for the razors (batteries).
After I was in another $100 in 3 month "disposable" batteries (yes, after trying to load balance at a time when I was traveling out of state regularly..) I was out. I recognized their business model and it isn't in the consumer's interest. It's what schick pioneered; let the customer pay-and-pay-and-pay.
I'd be very interested in another consumer focused brand to unseat them. They pulled an X-10; got the tech folks all into things but then pulled a boneheaded marketing/business strategy.
Would not buy again, to hell with them resurrecting themselves.
I'd rather by from GE/Phillips/Siemens when they have something that's well engineered and supported.
