The verdict
Buy the Kobra S1 ACE 2 Pro Combo.
8/10 vs Orange 4K V2's 6/10, and it wins 5 of 5 categories. This is the most aggressive 16-color enclosed CoreXY on the market. If you already know you want multi-color and don't want Bambu's walled garden, it is a near-automatic recommendation. For casual multi-color users, the 8-color Kobra S1 Combo remains the better value — 16 colors is overkill unless you print flags, pixel art, or multi-material models regularly.

What owners say
16 colors on an enclosed CoreXY [at this price] was not on my 2026 bingo card. Anycubic is swinging hard at Bambu's multi-color dominance.

Orange 4K V2 owner, r/resinprintingFine budget printer. Not as well-supported as Elegoo, but it gets the job done.

Pros & Cons
Kobra S1 ACE 2 Pro Combo
- +16-color capable (4 colors standard; 16 colors requires 4x ACE 2 Pro units purchased separately). Doubles the 8-color S1 Combo and quadruples the Bambu A1 Combo (4)
- +Fully enclosed CoreXY handles ABS, ASA, and engineering filaments without warping
- +44dB quiet mode is unusually low for a 600mm/s CoreXY — apartment-friendly
- −Brand new product — early adopter risk on firmware and ACE 2 Pro reliability
- −Anycubic slicer still trails Bambu Studio on automation and profile polish
Orange 4K V2
- +Better light uniformity than the V1 means fewer dark patches at plate edges
- +WiFi at this price is a feature the original didn't have
- +Compact enough to store in a drawer when not printing
- −4K resolution is dated: the Elegoo Mars 4 offers 7K for less with better community support
- −120x68mm plate is small even by entry-level standards
