Hi Brett,
I like cartridges, but they don't last two weeks for me...and that's if I skip a weekend.
At this point, shaving DE is a hobby...as is my single edge throat-cutter. If I have to do it, then I'll do it with style.

2017 QShave Merkur Futur clone
2016 Parker Travel with Lord L6 head
Shoot, the shaving hobby is cheaper than 1/2A flying!
PS My wife says she can tell the difference...and prefers the DE shave.
AY YI YI, some is still doing this?! Go get yourself a Gillette Mach 3. The blades are actually cheaper because you can use a single cartridge for about 3 months, so while it costs $5, you don't toss it after a week. And much less prone to cuts with far less care required.
