Three CASABREWS espresso machines sold new on Amazon in the US, reviewed and compared on one page: two narrow 51mm machines with pressurized baskets, and a 58mm machine that lets you set the temperature.
CASABREWS 3700 Essential

CASABREWS sells compact, low-cost espresso machines, and the three we have reviewed come in two kinds. The 3700 Essential and the CM5418 are near twins: narrow machines with a 51mm portafilter, pressurized baskets, a thermoblock heater and a manual steam wand, the CM5418 adding a pressure gauge on the front. The Ultra is wider and asks more of you: a 58mm portafilter with single-wall baskets as well as pressurized ones, four brew temperatures and a shot timer. None of them has a built-in grinder. Hands-on testers agree that the pressurized baskets make the two 51mm machines forgiving and that better espresso on them needs a better portafilter; where they disagree is the steam wands, and on the Ultra, the espresso itself.

A very narrow, low-cost first espresso machine with a steam wand both testers rated. Pressurised-only baskets cap the flavour until you buy a 51mm portafilter, the wand needs purging before the next shot, and TechRadar found its shots inconsistent and messy where Tom's Guide did not.

A consistent, forgiving first espresso machine for milk drinks in a very small space, with a proper steam wand. Pressurised-only baskets cap the flavour until you buy a new 51mm portafilter, the wand needs purging before the next shot, and the accessories are basic.

Rare features at its price, including 58mm single-wall baskets, four brew temperatures and a shot timer. Tom's Guide could not make microfoam and TechRadar could not get a clean-tasting shot, and both had to change the factory dose or volume.

All three heat with a single thermoblock, which warms water as it flows through, first for the shot and then, hotter, for steam. So none brews and steams at once, and each needs a moment to come back to brewing temperature after steaming. What separates them is the portafilter and whether you can set the temperature.
Schematics are simplified to show the water path; they are not drawn to scale.
Drawn to scale, so you can see how narrow the two 51mm machines are next to the wider Ultra before you measure your kitchen.
| Product | Width × depth × height | Weight | Water tank |
|---|---|---|---|
| CASABREWS 3700 Essential | 14.5 × 32 × 31.8 cm | 4.6 kg | 1.3 L |
| CASABREWS CM5418 | 13.9 × 31.2 × 30.4 cm | 3.9 kg | 1 L |
| CASABREWS Ultra | 31 × 26.2 × 33 cm | 6.2 kg | 2.2 L |
Dimensions are CASABREWS's own figures, from its product pages for the CM5418 and 3700 Essential and the Ultra's manual, which TechRadar's measurement of the Ultra matches closely. Weights: the CM5418's agrees across TechRadar, Coffeeness and Tom's Guide; the 3700 Essential's follows TechRadar and CASABREWS's store, while Tom's Guide prints about 3.7 kg; the Ultra's is from its manual. Tanks follow the specification tables: CASABREWS's 3700 Essential page also says 49 oz in its marketing text, and its Ultra page says 2.0 L where the manual says 2.2 L.
In our reading, some phrases in CASABREWS's listings and product pages mean less, or something different, than they suggest. Here is what each one turned out to be in the manuals and the hands-on evidence.
20-bar Italian pump
All threeWhat it isThe pump's rating, not the pressure at the coffee. No reviewer measured brew pressure on any of the three.
PID temperature control
CM5418 · 3700 Essential (CASABREWS's product pages)What it isYou cannot set the temperature on either machine, and Tom's Guide (3700 Essential) and Tom's Coffee Corner (CM5418) report no PID. We do not count it as a feature.
Custom brew temp
Ultra (Amazon listing)What it isFour fixed settings, 90, 92, 94 and 96 °C, chosen by holding the hot water button. CASABREWS does not call it PID; Tom's Guide and BrewCoffeeHome do.
Dual-wall filters for beginner-friendly extraction
CM5418 · 3700 EssentialWhat it isPressurized baskets only. They make crema at a small exit hole whatever the grind; better espresso means buying a 51mm single-wall or bottomless portafilter.
Built-in pressure gauge
CM5418What it isA dial with a marked espresso zone but no bar numbers. Coffeeness found the zone useful for spotting grind and tamping problems; Tom's Guide found it told it little.
Automatic purge after steaming
CM5418 (CASABREWS's product page)What it isAfter steaming, the shot buttons flash and the machine will not brew until it cools. The manual says to run hot water from the wand for about eight seconds, which is how Tom's Guide and Coffeeness cleared it.
Powerful steam wand
Ultra (Amazon listing)What it isTom's Guide found it too weak to make microfoam; TechRadar made silky microfoam once it adjusted to the wand's delayed start. It is a single-hole wand started with a button.
CASABREWS is a young brand: TechRadar reports that it was founded in 2020. It sells through its own store at casabrews.com, an official store on Amazon, which is the seller on the listings for all three machines here, and other retailers; its warranty page names Amazon, Target, Walmart and TikTok Shop among them, and gives a US address in Charlotte, North Carolina. Tom's Coffee Corner's specification list for the CM5418 gives China as the country of origin; the CASABREWS pages we read do not say where the machines are made.
The evidence is deepest for the CM5418, which has five hands-on reviews, including one from Coffeeness, which bought its own machine. The Ultra has three and the 3700 Essential two, and none of those reviewers says how they got their machine. On the two 51mm machines, testers consistently found the pressurized baskets forgiving, and most made good microfoam with practice, while Tom's Guide, TechRadar and Coffeeness all found the CM5418's plastic tamper inadequate. On the Ultra, Tom's Guide and TechRadar each hit a different problem: Tom's Guide could not make microfoam, and TechRadar could not get a clean-tasting shot. Tom's Guide also reports that CASABREWS revised the CM5418 in 2025, so older reviews may describe the earlier version. No source has multi-year reliability evidence for any of the three.
CASABREWS's US warranty is one year on every machine here. We found no safety recall for CASABREWS espresso machines in the US Consumer Product Safety Commission recall database, checked in October 2026.
All three tell you when to descale, and CASABREWS's warranty can exclude failures caused by skipped descaling, so it is worth doing when asked. Our CASABREWS descaling guide walks through each machine step by step.
Day to day, wipe and purge the steam wand after every use, which CASABREWS's Ultra page says the wand will not do for itself, and clear its tip with a pin if it clogs. Tom's Guide notes that no cleaning tablets come in the box with the CM5418 or the 3700 Essential. Our steam wand cleaning guide covers the routine.
CASABREWS sells several machines with similar names, and reviews do not always use the same ones.
When you buy a portafilter or basket, check that it names your model: Tom's Coffee Corner warns that De'Longhi's 51mm portafilters do not fit the CM5418, and CASABREWS's 58mm accessories are listed for the Ultra and the 5700 series.
For CASABREWS
All 3 reviews on this page are built from published evidence: CASABREWS's own specifications and listings, checked against independent reviews, rather than from our own testing. That leaves gaps desk research cannot close: long-term reliability, how a machine behaves after months of daily use, and details no reviewer has measured.
Hands-on testing is how those gaps close. If you represent CASABREWS, we welcome review units of the models on this page and of new models as they launch. Every unit we receive is considered for hands-on testing. Where a unit does inform a review, that review says so and names you as the supplier.
For most first-time buyers who mainly drink lattes and cappuccinos, the CM5418: forgiving pressurized baskets, a gauge to learn from and the deepest hands-on record. The 3700 Essential is nearly the same machine for less, with a bigger tank and no gauge. Choose the Ultra if you own a capable grinder and drink mostly espresso or Americanos. None of the 3 machines here holds a CoffeeLab award.
For a first espresso machine on a small budget, the evidence is encouraging but short. Testers made good milk drinks on the 51mm machines and found the pressurized baskets forgiving, while Tom's Guide and TechRadar each hit a different problem with the Ultra. CASABREWS gives a one-year US warranty, we found no US safety recall, and no source has multi-year reliability evidence.
They share the 51mm portafilter, the pressurized baskets, the 20 bar pump rating, the 1350 watt thermoblock and, CASABREWS told Tom's Guide, the same steam wand. The CM5418 adds a pressure gauge without numbers and has a 1 litre tank; the 3700 Essential has a 1.3 litre tank and costs less. Tom's Guide recommends the 3700 Essential, while TechRadar, testing both side by side, found the CM5418's espresso more balanced and less messy.
Yes, for whole beans. None of the three here has a built-in grinder, and CASABREWS says so for the Ultra. The pressurized baskets on the CM5418 and 3700 Essential work with pre-ground coffee, while the Ultra's single-wall baskets reward an espresso-capable burr grinder; Tom's Guide used a Eureka Mignon Specialita. Our grinder pairing tool suggests matches.
The CM5418 and 3700 Essential come with pressurized one-cup and two-cup baskets only. They build pressure at a small exit hole, which forgives grind and tamp but caps flavor, and TechRadar found no single-wall basket sold for the stock portafilter. Tom's Guide got much better shots after fitting CASABREWS's bottomless 51mm portafilter. The Ultra comes with both pressurized and single-wall 58mm baskets. See pressurized vs non-pressurized baskets.
One year in the US, from the original purchase date, for the original purchaser, on machines bought new from casabrews.com, an official CASABREWS marketplace store or an authorized retailer. CASABREWS may troubleshoot, send parts, repair, replace with a new or refurbished unit, or refund. Filter baskets and worn seals are excluded, and so can be failures from skipped descaling. Amazon buyers return through Amazon first.
