Wirsh Geimori T38 vs GU38
Build and Weight
The Wirsh Geimori Compact Conical Burr Grinder (T38 Plus) weighs 2.7 pounds and measures 9.1 inches tall. Its palm-sized, all-metal body is designed for cramped counters or travel. In contrast, the Wirsh Conical Burr Single Dose Grinder (GU38) is significantly heavier at 6.68 pounds and stands 12 inches tall. While both feature all-metal construction with wood accents, the T38 Plus is built for portability and space-saving. The GU38 offers a more substantial, stationary presence. If you prioritize a lightweight unit that fits in a travel bag, the T38 Plus is the clear choice. For a stable, heavy-duty countertop appliance, the GU38 provides more mass.
Burr Material
Both grinders use 38mm conical burrs, but the material specifications differ. The T38 Plus uses standard stainless steel burrs. The GU38 specifies high-nitrogen SUS420 stainless steel with an HRC58 hardness rating. This specific steel type suggests enhanced durability and sharpness retention for the GU38. The T38 Plus description mentions premium stainless steel but does not provide the alloy grade or hardness value. For users who want detailed metallurgical specs indicating long-term edge retention, the GU38 provides more technical assurance. The T38 Plus burrs are sufficient for general use but lack the detailed material certification found in the GU38 data.
Power Source
The GU38 is powered by a quiet 96W high-efficiency DC motor running at 190 RPM. This specific power source and speed rating offer insight into its grinding mechanics and noise profile. The T38 Plus description notes optimized motor operation that runs quieter than many competitors, but it does not list wattage, motor type, or RPM. Without these specific numbers, it is harder to compare the actual power efficiency or mechanical speed. The GU38 provides concrete data on its motor performance. If you need to know the exact electrical draw and rotational speed for compatibility or noise analysis, the GU38 is the better documented option.
Retention and Cleanup
The GU38 explicitly states less than 0.1g retention with RDT on a 20g dose. This low retention figure is critical for single-dose brewing to ensure freshness and reduce waste. The T38 Plus highlights anti-static technology and a magnetic dosing cup for a clean workflow, but it does not provide a specific retention measurement. While both are single-dose grinders with easy tool-free cleaning, the GU38 offers quantifiable proof of its retention performance. For users who track bean usage closely or brew small doses, the GU38’s documented low retention is a significant practical advantage over the T38 Plus’s general anti-static claims.
Travel Compatibility
The T38 Plus features worldwide voltage compatibility for 100-240V, making it safe to use in any country. Its compact dimensions (2.6 x 3.9 x 9.1 inches) and lighter weight make it ideal for RVs or travel bags. The GU38 data does not mention voltage range or travel-specific features. It is heavier and larger, which may limit its portability. If you plan to use this grinder while traveling or in different regions, the T38 Plus is the only suitable option. Its design is explicitly tailored for on-the-go use, whereas the GU38 is intended for stationary home use.

Buyers seeking quiet, efficient operation
