The Gemini 20 Precision Milligram Scale delivers laboratory-grade accuracy in a pocket-sized package. With its ability to measure in multiple units (grams, grains, ounces, carats) at milligram precision, this scale features a protective flip-down shield and magnetic storage case for longevity. Backed by a comprehensive 10-year warranty, it offers professional-quality measurement capabilities for those requiring exceptional precision.
The Gemini 20 Precision Scale delivers lab-grade accuracy at a bargain price, backed by an exceptional 10-year warranty that users confirm is honored. While not physically robust (handle with care), units consistently last 7-10 years with proper storage in the included case. The aggressive 60-second auto-off and poorly designed weighing pan frustrate users, but these annoyances are offset by remarkable precision that rivals equipment costing 10x more. Perfect for those needing milligram accuracy who can provide gentle handling. Not BIFL through ruggedness, but through performance consistency and warranty support.
The Gemini 20 Precision Scale offers moderate repairability with limitations. Users report it lasting nearly a decade with proper care, backed by a 10-year warranty, but with few user-serviceable internal parts.
Bottom line: Not built for internal repairs, but the comprehensive warranty, protective case, and long service life make it sustainably BIFL through manufacturer support rather than DIY fixes.
This precision scale punches way above its weight class — delivering lab-grade accuracy for decades if you baby it. The community consensus: handle with care and it'll outlast most electronics.
Bottom line: For milligram precision work, this is the community's go-to budget pick — just don't expect it to survive drops or rough handling like a true BIFL warrior would
The Gemini 20 scale comes with a substantial 10-year limited warranty from American Weigh Scales, which is remarkably generous for an electronic device in this price range.
Bottom line: This is an exceptional warranty for a $35 electronic device, and user reports confirm AWS honors it without significant hassle, though customers do bear initial shipping costs.
The Gemini 20 is remarkably well-regarded within BIFL communities as a precision milligram scale that delivers laboratory-grade accuracy at a fraction of the price of professional equipment.
Bottom line: While not physically indestructible, the combination of impressive accuracy, 10-year warranty, and protective storage case makes this a true BIFL item for those who need precision measurement capabilities.

Main product view
Recommended: As Needed•Calibrate and clean the Gemini 20 whenever accuracy issues are noticed, after moving location, or if exposed to dust or contaminants.
Use a soft, dry, non-abrasive cloth to wipe the weighing platform and exterior. Avoid liquid cleaners, which can damage sensitive electronics. Keep the scale free of dust and debris for accurate readings.
Calibrate the scale regularly using the included 10g calibration weights; place the weight on the center of the platform and wait for stabilization. Avoid overloading, shaking, or dropping the scale, as this can permanently damage internal sensors.
Recommended Products
Store the scale in its carrying case in a clean, dry, vibration-free location away from temperature extremes and air currents. Allow the scale to acclimate to room temperature for at least one hour before use.
