My favorite mod is the astro clone, have used several high end
devices and rather stick with this $20 clone. hits hard, great switch, small size, smooth threads etc... The high end stuff i tried were chiyou, chi megan, 4Nine, 2six. All nice but all of them have needed repairs/ still have issues they are having a hard time figuring out. My astro just keeps trucking right along

Even if it died, the full replacment would be cheaper then a high end mod repair.
Just my thoughts, im sure ill get some haters but I like my little clone. Now if you want to pony up the money grab the auth astro
