Quick answer: Choose the Opal Mini when counter width is the main constraint. Consider Mini Pro when its side tank and extra width suit your refill routine. Check the full model number: the Mini linked here, P4NM20KZLG, lists Wi-Fi, so “buy Pro to get Wi-Fi” is not a valid reason to upgrade between these two listings.

The Mini family makes more sense as a space-and-refilling decision than a contest over the word “Pro.” GE introduced Mini, Mini Pro and Mini Pro+ in July 2026. This guide separates the family announcement from the exact US variants connected below, using information checked September 22, 2026.
Mini, Pro and Pro+: start with the exact version
| Version | Model reference | Dimensions, H × W × D | Practical distinction |
|---|---|---|---|
| Mini, Stone Grey | P4NM20KZLG; linked Amazon variant | 14.56 × 8.6 × 15.6 inches | Top fill; narrow cabinet; listing includes Wi-Fi |
| Mini Pro with side tank | P4NM25LZSG; linked Amazon variant | 14.56 × 11.6 × 15.6 inches | Side-tank configuration; listing includes Wi-Fi and colored bin lighting |
| Mini Pro+ | P4NM25QZSS; official GE reference | 14.56 × 11.6 × 15.6 inches | Full stainless finish; compare the exact bundle |
Dimension sources: GE’s P4NM20KZLG, P4NM25LZSG and P4NM25QZSS pages. Features on the linked Mini and Pro are also checked against their exact current Amazon listings, not assumed from another suffix.
The price ladder and the space tradeoff
GE’s family announcement lists launch prices of $279–$299 for Mini, $379 for Mini Pro and $399 for Mini Pro+. These are launch references, not a promise of today’s checkout price. It describes the Pro and Pro+ as side-tank versions, with Pro+ in full stainless steel.
The table shows the tangible tradeoff: the side-tank configurations add three inches of width. Mark that outline on your counter and check whether it interferes with your coffee station, outlet or cabinet access. Do not assume an appliance fits simply because its height is below the cabinet; filling and ventilation need room too.
We would start with the narrow Mini if width is scarce and top-filling is convenient. The Pro is worth considering when its tank arrangement is useful enough to justify the space and price difference. The Pro+ needs its own finish-and-bundle comparison; its name alone does not establish more daily ice.
Production is not storage—and GE’s figures need context
The current Mini and Pro listings connected here advertise up to 36 lb/day and a 2 lb bin. GE’s launch announcement also uses 36 lb/day. However, the detailed capacity table on the official Pro+ page checked for this update lists 34 lb/day, while the Opal family overview advertises up to 36 for that version. We have not resolved that documentation discrepancy with GE.
Do not use that small difference as a decisive ranking between tiers. More useful questions are how many drinks you serve at once and how often you are willing to collect ice. A daily production estimate does not mean the bin holds a day’s output, or that every room and water temperature will produce the headline amount.
The Pro+ specification page does provide first-ice timing: five minutes at 60°F water and 70°F ambient. That condition belongs with the claim. It also means a blanket statement that GE publishes no first-ice information is out of date.
Maintenance features do not establish long-term reliability
GE’s announcement describes easier front access, top filling and a drain-and-dry system. These are useful design details to inspect before buying. They do not prove that a unit will remain trouble-free for years or make cleaning optional.
Use the exact model’s owner’s manual to check sanitizing, descaling and ventilation requirements. Think through where you will drain the machine and reach the parts that need attention. A convenient setup is one you can maintain without dismantling the rest of your counter.
Frequently asked questions
Does the base Mini lack Wi-Fi?
Not the P4NM20KZLG listing linked here: it includes SmartHQ Wi-Fi features. Check the complete model suffix and listing rather than applying one family’s feature summary to every variant.
Does Mini mean the entire larger Opal line is gone?
No such conclusion follows from the Mini launch. GE’s current family overview lists larger Opal options alongside Mini. A model-specific clearance or manufacturing notice should not be generalized to the entire range, and clearance wording does not prove an all-time lowest price.
Should I buy a larger Opal instead?
Compare the exact bin, tank and footprint with your routine. Our updated countertop ice-maker comparison includes an Opal Ultra XL and alternatives for bullet and clear ice. If you want nugget ice in less counter width, this Mini comparison is the more relevant starting point.
