I've heard that the obsidian is constructed a lot like the achilles. Back when I was new to cigars I bought a bundle of achilles cause they were cheap and almost threw the whole thing away. Every single stick was WAY too tight and went out at least halfway even with constant drawing. The bundle lasted about a year and a half, but even the last few were horribly constructed. Flavor was pretty good on them, but the construction killed them for me.
