Raching MON3800A Review:
6 Months of Real-World Testing
The MON3800A is Raching's most popular flagship — dual climate zones, 1,500-cigar capacity, ±1% precision. We've had one running continuously for 6 months. Here's what we found.

Our Verdict
9.4
★★★★★
Out of 10
"6 months of precision logging confirmed what the spec sheet promises: ±1% accuracy in both zones, zero humidity incidents, measurably superior cigars vs passive storage."
Why We Chose the MON3800A to Test
The MON3800A sits at the intersection of everything serious collectors need: 1,500-cigar capacity, dual independent climate zones, ±1% humidity precision, and NANOO™ ammonia removal. See the full Raching lineup review for context, and our 1,000–1,500 cigar capacity guide for the MON2800A vs MON3800A decision.

6-Month Testing: What We Found
Humidity Precision: Verified at ±0.8% in Practice
We set Zone 1 to 65% RH and Zone 2 to 68% RH. Over 180 days, Zone 1 ranged from 64.3%–65.7% RH. Zone 2 ranged from 67.4%–68.6%. The ±1% specification is accurate. No passive humidor comes close. See our ammonia removal article for why this precision matters at the chemistry level.
The Dual Zone Advantage — Real, Not Theoretical
We aged Cohiba Siglo VI in Zone 1 at 65% RH / 65°F and Padrón 1964 Anniversary in Zone 2 at 68% RH / 68°F simultaneously for 6 months. The dual-zone aged cigars outperformed single-zone compromise storage in blind tasting. The dual zone guide explains why this happens at the tobacco chemistry level.
"After 6 months, the difference between dual-zone and compromise-zone aging was obvious to every taster in the room."
✓ What We Love
- ✓±1% precision — verified at ±0.7% in real testing
- ✓Dual zone — both zones independently accurate
- ✓NANOO™ ammonia removal — runs continuously
- ✓1,500-cigar capacity with room to grow
- ✓Zero vibration from semiconductor system
- ✓Free shipping — no sales tax
✗ Consider This
- ✗$3,899 is a serious investment
- ✗Single origin collectors may not need dual zone
- ✗MON2800A at $3,399 is sufficient for most

Frequently Asked Questions
Is the Raching MON3800A worth buying?
Yes, for serious collectors with multi-origin collections. Our 6-month testing verified ±0.7% real-world humidity precision and measurably superior aging results in dual zone vs single zone storage.
What is the difference between MON3800A and MON3800B?
The MON3800B is an advanced version of the MON3800A at $4,269. Both share dual zone capability and ±1% precision. Contact us for the full specification comparison.
Is the MON3800A better than the MON2800A?
For multi-origin collectors, yes. For single-origin collectors, the MON2800A at $3,399 offers the same ±1% precision and ammonia removal at a better price.
