The CM5418 is Casabrews’ step-up machine from the 3700 Essential, adding PID temperature control and a milk frother wand for $125.99. TechGearLab tested it and scored it 69 out of 100, ranking sixth of eleven espresso machines in its lineup — a middling result driven largely by one specific part: the basket doesn’t seat properly in the portafilter.
PID control, but not one you can adjust
TechGearLab confirmed the CM5418 has PID temperature control, which is the feature that separates it from cheaper thermoblock machines like the Casabrews 3700 Essential — a PID actively holds brew temperature at a set point rather than cycling on and off around it, which generally means more consistent shot-to-shot temperature. Other reporting on this model notes the temperature is not user-programmable, meaning you get the stability of PID control at a fixed factory setpoint rather than the ability to dial in your own target temperature the way a machine like the Diletta Bello+ allows.
The basket doesn’t sit right in the portafilter
This is TechGearLab’s central complaint. Rather than a spring clip holding the basket firmly in the portafilter, the CM5418 uses a nub-and-groove design that has to be threaded into place, and testers found the basket \”wobbles and clacks around noisily\” once seated. Beyond being distracting, that looseness made it harder to knock the used puck out cleanly and created a real risk of the basket itself falling loose into the knock box during that process. It’s a fit-and-finish problem specific to one part, not a sign the machine can’t pull a shot — TechGearLab still measured a 21% extraction yield and called the output consistent — but it’s the kind of daily annoyance that drags a review score down.
Pressurized baskets only
The CM5418 ships with double-walled pressurized baskets in one- and two-shot sizes, and TechGearLab found no compatible non-pressurized option available for it. Pressurized baskets are more forgiving of grind and dose mistakes and reliably build crema, which suits a beginner, but they cap how much flavor complexity the machine can produce compared with a single-wall basket used with a properly dialed-in grind. If you want to grow into that style of shot later, this machine won’t get you there without buying into an uncommon 51mm grouphead size that limits aftermarket accessory options.
Where the build feels the price
TechGearLab described the overall construction as economical rather than premium, singling out the portafilter handle as hard plastic that \”doesn’t feel especially pleasant in the hand\” and the included tamper-scoop as too lightweight for proper tamping technique. The steam wand also drew a mixed note: low steam pressure means it takes longer to build froth than testers wanted, though they said it eventually produces smooth microfoam. No milk jug is included, so budget for one separately. The machine includes a 34 oz water tank capacity.
Before you buy
- Expect the basket to wobble in the portafilter and to require care when knocking out the used puck.
- Budget for your own tamper and a milk jug; TechGearLab found both included accessories lacking.
- Know that the 51mm grouphead is a non-standard size, which limits which aftermarket portafilters and baskets fit.
- If you want an adjustable brew temperature rather than a fixed PID setpoint, look at a machine that advertises programmable temperature control instead.
