I bought two used boards both requiring some maintenance. A stealth w/ 1250mi and a v2 dual+ w/ 350mi. Both physically look about the same condition, maybe the stealth in slightly better physical condition. Battery on both is XR and about 2mo old on the stealth. I have not compared the total range on both yet (probably really hard to test due to variables). Ultimately it will come down to ride comfort (so far not noticeable to me). I care about comfort and longevity. The stealth has about 6mo left on the official warranty. I've read lots of great stories about after warranty support, so maybe not a big deal but worth mentioning. Don't know if this matters but I'm a noob.
