Agreed. In the case of the Razorock Adjust, that was offered on sale for just $7.99 this past holiday season, even if it only lasts a few years it's still a great value. It's well chromed so it ought to be good for 5-10+ years at least. My oldest DE, a 4+ year old Weishi 9306 Long Handle is still going strong with no corrosion. For these razors I suspect the biggest risk is if they get dropped and lose blade alignment as a result.One should hope that the new mechanisms will stand the test of time as well as the Gillettes certainly seem to do.
As a premium razor selling for over $100 the T2 will hopefully last for decades for those who own one.
Nice to have some current production options. Both of these introduced over the past 2-3 years.
For comparison the Super Adjustables probably sold for $20-$30 in today's dollars adjusted for inflation.
