The buying question
Will the narrow K-Slim layout and three brew sizes suit your counter and routine, or will the standard K-Supreme's repositionable reservoir and additional brew controls be useful?
K-Slim has a 4.76-inch body width and 46-ounce removable tank. K-Supreme has a larger 66-ounce tank that can sit at the side or rear, plus an additional 6-ounce size, Strong button, and hot-over-ice control. The listed K-Supreme unit is Renewed.
Quick verdict
Choose Keurig K-Slim (K900, White) if
- You need the brewer body to stay under 5 inches wide and 8-, 10-, and 12-ounce buttons cover your usual cups.
Choose Keurig K-Supreme (KSK910BK-cr, Black, Renewed) if
- You want to place the removable 66-ounce reservoir at the side or rear, or you will use the 6-ounce, Strong, or hot-over-ice settings; verify the seller's Renewed condition and terms for this exact offer.
When the recommendation changes
- If the counter opening is narrower than the K-Supreme's documented 6.36-inch rear-reservoir width but at least 4.76 inches, the K-Slim is the documented fit candidate; measure clearance and pod-handle access before buying.
- If reservoir location is the constraint, compare the K-Supreme's side and rear dimensions against the available depth and width rather than assuming its alternate position fits.
- If you do not need the extra controls or reservoir layout, compare the current exact-offer condition, return terms, and checkout total; this comparison has no long price history.
The differences that matter
Counter Fit And Reservoir Refill Workflow
Keurig K-Slim (K900, White)
K-Slim body width 4.76 in; removable reservoir capacity 46 oz.[1]
Keurig K-Supreme (KSK910BK-cr, Black, Renewed)
K-Supreme removable 66 oz dual-position reservoir; footprint listed as 7.85 in wide at the side or 6.36 in wide at the rear.[3]
What this changes: The K-Slim is the documented narrower-body fit; K-Supreme offers two tank positions and more water between refills. Actual counter fit depends on available width, depth, and overhead clearance.[1, 3]
Brew Size And Strength Control Workflow
What this changes: The additional K-Supreme choices matter only if the buyer will use them. They establish feature availability, not a measured taste, strength, extraction, or cold-brew result.[1, 3, 4]
Best for your routine
A strict body-width limit under 5 inches
Best fit: Keurig K-Slim (K900, White)
Based on listed features, not comparative testing.
The official K-Slim page lists 4.76 inches wide; the standard K-Supreme page lists 7.85 inches with its tank at the side and 6.36 inches with it at the rear. Check full available depth and handle clearance too.
A routine that uses a 6-ounce cup, Strong, or hot-over-ice setting
Best fit: Keurig K-Supreme (KSK910BK-cr, Black, Renewed)
Based on listed features, not comparative testing.
Those controls are documented for the standard K-Supreme; K-Slim lists 8-, 10-, and 12-ounce buttons. Strong and hot-over-ice are modes, not proof of better taste or a cold-brew cycle.
Value and trade-offs
One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.
A higher checkout total is only relevant if the K-Supreme reservoir arrangement or additional controls fit your routine. The K-Supreme offer here is Renewed, so compare its seller condition, return and warranty terms with the exact K-Slim offer rather than assuming equivalent condition.
No price trend is asserted. Compare current checkout totals and seller terms for the exact models and condition.
Limitations
- The K-Supreme offer here is identified as Renewed, part KSK910BK-cr. Keurig's standard K-Supreme materials do not establish this seller's refurbishment grade, included accessories, warranty, return policy, or previous use. Check the seller terms before buying; do not assume the standard new-product warranty applies.
- The Strong control is a published brew setting; these sources do not establish comparative taste, extraction, or real-world brew-quality results. Hot over ice is not described here as cold brew.
- Measure your counter and overhead clearance for the open pod handle. The K-Supreme dimensions vary with reservoir position, and the K-Slim page separately lists handle-open height.
Questions shoppers ask
Does the K-Slim fit a counter opening under 5 inches wide?
The official page lists the brewer at 4.76 inches wide and describes it as less than 5 inches wide. Allow room to position it and operate the handle; the page lists the open-handle height separately.
Does the K-Supreme offer include the standard new-product warranty?
The K-Supreme offer here is Renewed. Keurig's standard product materials do not establish this seller's refurbishment grade, warranty, return terms, or included accessories. Check the seller terms before checkout.
Is K-Supreme's hot-over-ice control the same as cold brew?
The official page describes a hot-over-ice brew setting. The materials reviewed do not describe this control as a cold-brew cycle.
