Key Details
The Karu 12 versus the Karu 2
The Karu 2 is the direct successor to this oven, and the upgrade is worth having if budget allows. The built-in thermometer on the Karu 2 is not a cosmetic addition -- it changes how you manage cook sessions because you stop guessing when the stone is hot enough. Without it, you are relying on timing estimates and experience. First-time pizza oven owners in particular will get more consistent results from the Karu 2.
The Karu 12 still produces excellent pizza. The core technology is the same, and buyers who already own one or who find a compelling deal have no reason to feel they are settling.
Pros and Cons
Pros
- Lower price than the Karu 2
- Multi-fuel flexibility that the Koda line cannot match
- Proven design with years of owner reviews to reference
- Portable 12-inch footprint
Cons
- No integrated thermometer -- you estimate preheat readiness
- Karu 2 has better heat retention and door design
- Gas burner sold separately
Bottom Line
Consider the Ooni Karu 12 if you want multi-fuel flexibility at a lower price than the Karu 2. The cooking results are nearly identical. The Karu 2 is the cleaner buy if budget allows, but the Karu 12 is a solid fallback.
