The bottom line
Here's what I'd tell a friend
What you should know first
R3 scores this 3.4/10 (Below Average), but this score comes with major caveats. The Vitamix 48oz Stainless Steel Container is an accessory, not a complete blender -- it has no motor, which causes wattage and noise to default to 1/10. The 304 stainless steel jar also scores 1/10 due to a rubric gap (no band exists for stainless steel), despite being objectively among the safest food-contact materials available. NSF certification (7/10) is the strongest in this blender set. The score would be substantially higher if the rubric accommodated stainless steel and if this were evaluated as an accessory rather than a standalone blender.
Go for it if...
You already own a Vitamix motor base and want to eliminate all plastic food contact during blending
Material safety is your top priority -- 304 stainless steel is chemically inert with zero leaching at any temperature, and NSF certification verifies the material composition
You want a container that's essentially unbreakable -- stainless steel won't crack, chip, or shatter like glass
