Casabrews 3700 Essential
The Casabrews 3700 Essential is the cheapest way into real espresso in this catalog after the Stilosa: a manual machine with a 20-bar pump, 1350 W heater and a 43.9 oz tank, stated on the Amazon listing, for about $140 with street pricing between $110 and $180. There is no grinder and the milk system is a plain steam wand. Our engine scores it 5 for espresso, 4 for milk and 3 for ease, for an overall 4 out of 10 - tied with the De'Longhi Stilosa for the lowest score of the nineteen machines we track. What decides it is honest: this is a machine you buy because of what you are willing to spend, not because of what it does.

A 4 out of 10 is the floor of this catalog
Habilytics scores are relative to the machines we track, not to some absolute idea of espresso. A 4 overall means that of the nineteen espresso machines in this catalog, nothing scores lower - the Casabrews 3700 Essential is tied at the bottom with the De'Longhi Stilosa. It is the same story on every dimension. Its 5 for espresso is the joint-lowest espresso score here. Its 4 for milk is the joint-lowest milk score here. Its 3 for ease is the joint-lowest, shared with the Stilosa and the Gaggia Classic Evo Pro. That is not a scoring accident. The engine reads three things: what the machine can put in the cup, what it can do with milk, and how much work it asks of you. This machine is manual, has no grinder, and offers a plain steam wand. On all three inputs it sits at the bottom of the range, so it scores at the bottom. None of that makes it a bad purchase. It makes it a cheap one, with the compromises a cheap one carries. The useful question is not whether 4 is a good score. It is whether the $360 gap between this and the cheapest machine here with a grinder is money you want to spend.
20 bar is the wrong number to shop on
The listing leads with a 20-bar pump, and it is the highest pump rating stated anywhere in this catalog. It buys you nothing in the score. The De'Longhi La Specialista Opera is rated 19 bar and scores 9 for espresso against this machine's 5. The Dedica and the Stilosa are both 15-bar and score 6 and 5. The pump number and the espresso score are not moving together, because pressure is not the constraint on a $140 machine. The same goes for wattage. This unit draws 1350 W; the Dedica draws 1300 W and scores a point higher for espresso. Heater power sets how fast the machine gets to temperature, not how good the shot is. What actually separates the top of this catalog from the bottom is grinding and dosing. Every machine here scoring 8 or 9 for espresso either includes a burr grinder or, in the Gaggia Classic Evo Pro's case, hands you a 58 mm commercial portafilter and expects you to bring one. This machine does neither. Fill its basket with supermarket pre-ground and the 20 bar on the box will not save the shot. That is most of why it scores 5.
Budget for the grinder, or do not buy this at all
The 3700 Essential has no grinder, and that is not a detail you can defer. Espresso needs a burr grinder with fine adjustment, and our engine's own budgeting rule adds $100 to $200 for one on top of any machine that lacks it. On a $140 machine, that roughly doubles the real cost of the setup, and it is the single most common way people end up disappointed by a cheap espresso machine. Run the number honestly and it still works. The 3700 Essential plus a decent burr grinder lands somewhere around $240 to $340. The cheapest machine in this catalog that includes a grinder is the De'Longhi Magnifica Start at $500. Even at the top of that range you are well under the all-in-one entry point, and you own a grinder you can carry to a better machine later. Run it dishonestly - buy the machine, keep using pre-ground from the supermarket - and you have spent $140 to make weak, fast-flowing coffee that will convince you that you do not like espresso. If the grinder is not in the budget, this is not a purchase to make yet.
Milk 4 and ease 3: where it actually hurts
The milk score of 4 and the ease score of 3 are the two numbers to sit with before buying. Milk first. The 3700 Essential has a manual steam wand, the least automated of the three milk systems in this catalog. The Breville Bambino Plus is the same idea a few tiers up, semi-auto and still no grinder, but its auto-texturing wand makes microfoam hands-free and scores 8 for milk against this machine's 4. Carafe systems like LatteGo and LatteCrema score 7 and rinse in seconds. A manual wand can beat any of them once your technique is there, but that is a skill you build: purging, positioning, listening for the stretch, wiping the wand every single time. Expect a couple of weeks of ugly practice lattes. If milk drinks are most of what you make, a 4 is a real warning and not a rounding error. Ease next. A 3 means this machine asks for everything: grind, dose, tamp, pull, texture, clean, every cup. There is no assisted tamping, no preset, no button that makes a drink. That is the same score the $450 Gaggia Classic Evo Pro carries, and it is what people are describing when they say a cheap espresso machine ended up in a cupboard after a month.
When this is the right buy, and when the Stilosa is
There is a real case for this machine. It is the cheapest way to find out whether you actually want the espresso hobby, in a footprint that fits a dorm desk or an office corner, and the 43.9 oz tank means you are not refilling it every second drink. If the answer turns out to be no, you are out $140 rather than the $500 an all-in-one would have cost. If the answer is yes, the grinder you bought alongside it moves to whatever you upgrade to. The harder question is the De'Longhi Stilosa, because our engine cannot tell them apart. Same 5 for espresso, same 4 for milk, same 3 for ease, same overall 4. Same manual format, no grinder, manual steam wand. The Stilosa sells for about $110 against this machine's $140, and its listing carries 13,000-plus reviews and roundup consensus as the safest cheap entry. The Casabrews answer is a stated 43.9 oz tank, a higher stated pump rating the score does not reward, and Amazon best-seller standing for a brand that mostly lives there. At full price, take the $30 saving. If the 3700 Essential is discounted toward $110 and the Stilosa is not, they are the same buy.
Who it's for / who it's not
Who it's for
- Testing whether you like the espresso hobby before committing $500 to a machine with a grinder
- Dorm rooms and office corners where counter space and budget are both genuinely tight
- Buyers who already own a burr grinder, or will buy one at the same time
- Straight espresso and americano drinkers who will rarely touch the steam wand
Who it's not for
- Households whose daily order is lattes or cappuccinos - a 4 for milk is the catalog floor
- Anyone unwilling to add a burr grinder - pre-ground coffee wastes this machine entirely
- Anyone wanting coffee at a button - it scores 3 for ease, the joint-lowest here
