I used to ignore little purple knick-knacks in ARC, then a buddy told me to start tracking the Ion Sputter and it flipped my whole route planning. If you're still sorting your stash and wondering what's "actually" worth a slot, it helps to look at community lists like ARC Raiders Items and then decide what you'll risk an extraction for. The Sputter doesn't look like a big deal, but the moment you need its parts, you'll feel that pressure fast.
On paper, it's simple: 1.5 kg, Epic rarity, stacks to three. In practice, it's one of those items that changes how you play the middle stretch of progression. Selling is tempting because 6,000 coins per unit is clean, easy money. Three in a stack and you've basically paid for a solid kit. The catch is you'll hit a wall later if you treat every Sputter like pocket change, because it's also a shortcut into materials you're going to wish you'd saved.
If you're broke, sure, sell one and keep moving. But most of the time recycling is the smarter call. Break a single Ion Sputter down at the Raider Den and you get 4 Voltage Converters plus an Exodus Module. Those aren't "nice to have" items; they're the stuff that stands between you and the gear everyone's chasing. If you've got your eye on tougher defensive options or higher-tier weapons, you'll burn through those components way quicker than you expect.
Stella Montis is the consistent play, and it's not because it's fun and relaxing. It's because the spawns line up with dense loot containers and repeatable routes. Most players sprint toward The Assembly, then head for the northern control rooms on the second floor. Check raid drawers first, then any breachable cabinets. That's where I've seen them show up the most, but it's also where you'll meet other raiders doing the exact same thing. If The Assembly is a war zone, swing northwest to the Assembly Workshop instead. It's packed with lockers, and you can loot quicker and bail before the map wakes up.
The ugly truth is the drop rate can feel personal. You'll hear stories of 30 or 40 expeditions for a couple of Sputters, and yeah, that happens. Running light helps: less weight, faster resets, more chances to slip away when footsteps hit the hallway. Try not to fire unless you have to, because gunshots pull machines and players in the same way. And if you're short on coins or just want to smooth out the gearing cycle between raids, plenty of folks use U4GM to pick up game currency or items so they can focus on the runs that matter instead of scraping together a loadout.
