On hot days the desire for cold drinks rises — and with it the demand for ice. The freezer tray rarely delivers: already empty, not yet frozen, or lost somewhere between ice cream and barbecue supplies. Ice cube machines promise fresh ice at the press of a button within minutes — and where German brands like Gastroback, Caso and Klamer once led the market, countless unknown Chinese brands now dominate online retail with near-identical machines. A full comparative test sorts the sovereign performers from the quickly overwhelmed.
How These Machines Actually Work
Three facts frame every purchase. First, the speed comes from chilled metal pins on which water freezes directly — producing, strictly speaking, hollow cones rather than cubes. Second, that short freezing time leaves the ice far warmer than freezer ice: hovering around zero degrees instead of minus eighteen, it melts noticeably faster. Third, no machine in the class actively cools its storage basket — the first cubes shrink quickly, and only once the basket fills does the accumulated mass keep itself cold.
Test Winner and Value Champion: WIE Ice Cube Machine
The WIE machine took the overall win and the price-performance crown simultaneously. For around 80 euros it combines speed, frugality and simplicity in a way no rival matched: first ice in a measured 6 minutes 43 seconds — at the head of a field where five to eight minutes is the usual promise — and just 9 watt-hours for the first batch. The first cubes emerge small but grow with every cycle at unchanged pace, passing the 50-cube mark in around 40 minutes. Controls are uncomplicated, indicator lights cover water level and basket, a self-cleaning function eases maintenance, and the compact footprint suits kitchen counters and small balconies. The one genuine weakness is noise: at 63 decibels it runs somewhat louder than its German rivals. Anyone who can live with that gets a fast, frugal and surprisingly cheap ice maker that earned its title.
For Big Parties: Gastroback Bartender Pro

Regular high-volume users are well served by the Bartender Pro at around 190 euros. Its 2.8-litre tank and 1.5-kilogram basket are the largest in the field, sharply reducing refill and emptying rounds — valuable in continuous operation, since every tested machine signals empty tanks and full baskets only by indicator light, never by sound. Performance convinces: 56 cubes in around 51 minutes, with the first batch barely melted as the second finished — not a given in this field. Operation looks complex but proves largely intuitive after brief acclimatisation; the stainless housing demands care, while an automatic cleaning function eases the internals. One important ritual: let the machine stand upright for 24 hours before first use so the coolant settles.
Fast and Frugal: Caso Ice Master Pro
Third place goes to the Caso Ice Master Pro at around 120 euros, on the strength of low power draw and brisk production: first cubes after 8 minutes 15 seconds, settling to a constant nine-minute cycle with cubes growing slightly each round. Operation is deliberately minimal — power switch and size button, nothing more — but a self-cleaning function is equally absent: regular washing-up liquid cleaning and descaling are the price, made fiddlier by the convoluted interior. Filtered water reduces the workload. The housing mixes quality-feeling stainless steel with plastic, marred in the test by a viewing window already scratched on unboxing.
Ten at a Stroke: Klamer Ice Maker

At around 160 euros the Klamer sits in the upper midfield with a 2.1-litre tank and 600-gram basket — adequately sized for daily use and small gatherings. Its party trick makes it the fastest machine in the field over volume: as the only model producing ten cubes per cycle, it needed just 47 minutes 54 seconds for 50 cubes.
German Brands or Online Newcomers?
The market's central question gets a measured answer. The unknown-brand machines flooding online retail share their basic construction with the established names — same pin-freezing principle, same plastic-heavy builds, same indicator-light interfaces — and the test winner itself comes from exactly this newcomer category. The German establishment defends itself on different ground: bigger tanks, quieter running and sturdier housings (Gastroback), lower energy draw per litre (Caso), clever cycle engineering (Klamer). The honest conclusion: the China-junk stereotype did not survive the test, but neither did the assumption that all the lookalike machines perform alike — the field behind the winner spread widely in speed, noise and build.
Care and Maintenance
Whatever the brand, longevity follows the same rules. Descale regularly — filtered water stretches the intervals dramatically — and favour machines with self-cleaning programmes if the inner architecture looks convoluted, because hand-cleaning angled freezing chambers is the chore that retires these machines early. Empty tank and basket after every session: standing water breeds exactly what nobody wants near their drinks.
Storage and Serving Reality
Because the cubes hover near zero degrees, plan around their impatience: serve immediately, or transfer batches to the freezer where they harden into proper long-life cubes. For parties, production maths beats basket size — a machine cycling every seven minutes refills glasses faster than any single basket-load suggests.
What the Test Measured
Every machine faced an identical practical course. Equipment scoring covered tank volume, storage capacity, daily output, cube-size options and details from housing material to cable storage and bundled ice scoops — noting that not one device in the field offers an acoustic alert. Handling began with the manual's clarity and cleaning instructions, continued through control logic, and ended with the honest question of post-party cleaning effort. The technical examination measured energy per batch and per 50 cubes, timed under realistic room-temperature conditions, plus noise levels — where differences are real for anyone running the machine on a terrace or in the living room.
Power and Placement
Two practical notes round off the picture. Consumption differences compound over a summer: the winner's 9 watt-hours per batch sets a benchmark that the thirstier machines double, and anyone running daily production through July will see it on the meter. Placement matters too — these machines vent heat sideways and behind, so a hand's width of clearance keeps cycle times honest, while direct sun on the housing visibly stretches them.
Buying Advice in Brief
For most households the 80-euro test winner is simply the answer: fastest, cheapest to run, easiest to live with. Hosts who pour drinks by the dozen should pay for the Gastroback's tanks; the impatient with sensitive ears take the Caso; volume-per-hour maximisers take the Klamer. And whichever machine wins your counter: use the ice fresh — these are convenience machines, not freezers.
