We earn affiliate commission on every infusion machine on this site. We're still going to tell you that most people landing on machine reviews don't need one yet. The right answer for the majority of home edible makers is $40 of kitchen basics and an evening of practice. Here's how to tell whether you're the exception.
The honest split
Our read of the funnel: roughly 30% of buyers genuinely benefit from a machine (high-frequency batchers, smell-constrained households, tincture makers). The other 70% would get more value from $40 of better tools and a Saturday afternoon. This page is for the 70% — and the 30% who want to make sure they're really in the 30%.
The three honest tests
Hit 2 of 3 and a machine probably pays back. Hit 0 of 3 and it's a hobby purchase, not a tool.
You batch twice a month or more. This is the cadence break-even math actually works at. Once a quarter? The machine sits in a cabinet. The calculator below shows your specific number.
Smell is causing real household friction. Apartment, roommates, kids, neighbors. A sealed machine + Mason-jar decarb is one of the few combos that compresses smell down to "30 seconds at lid-open" — see low-smell edible setup.
You've already burned $40+ of flower to inconsistent batches. If you have a clear memory of a batch that came out unusable, you're feeling the retention-variance problem a machine actually solves.
Run YOUR numbers
Generic break-even is "about 7 batches at default inputs." Your numbers are different. Put your flower cost, batch size, and machine you're eyeing into the calculator and watch the break-even line move:

What to buy first if the answer is "not yet"
The $40 trio below fixes more bad batches than any $300 machine. We see this repeatedly: people who can't get a consistent stovetop batch buy a machine expecting it to fix the problem, and end up with the same inconsistency because the root cause was wrong flower weight or wrong oven temp — neither of which a machine fixes.
If the answer is "yes," here's the path
Take the 6-question Machine Finder — it picks based on your batch size, smell tolerance, and what you make.
Cross-check with the full decision matrix if you want to see all four side by side.
If price is the constraint, consider a used LEVO II or MB2e on eBay — $120–$180 in good condition with the original temperature accuracy intact.

Frequently Asked Questions
Honestly, do most home edible makers need an infuser?+
No. Our read of the buying funnel: roughly 60–70% of people who land on infusion-machine reviews would be better served by a $40 scale + thermometer + an evening with a saucepan. Machines win clearly for high-frequency batchers, smell-constrained households, and tincture makers — three real but narrow groups.
What's the strongest argument FOR a machine?+
Consistency at scale. A sealed machine running the same cycle on the same weight of flower produces the same butter every time. Stovetop variance can range from 45% to 70% retention batch-to-batch depending on temperature control, even with the same person cooking. If you dose-test seriously, that variance is the actual problem a machine solves.
What's the strongest argument AGAINST?+
You haven't mastered the cheap step. Buying a machine before you can reliably hit a 240°F decarb and a 165°F simmer with a thermometer means you'll blame the machine when the real issue was technique. The $40 starter tools teach you what 'good' looks like — then a machine automates a process you already understand.
How do I know if I'm in the 30% that benefits?+
Three checks: (1) batching twice a month or more, (2) smell is causing real household friction, (3) you've already burned $40+ of flower to inconsistent batches. Hit 2 of 3 and the math on /tools/manual-vs-machine probably works for you. Hit 0 of 3 and a machine is a $300 hobby purchase, not a tool.
Is buying a used LEVO/MB2e on eBay a real option?+
Yes — and the better budget alternative to the cheap Amazon knockoffs. Used LEVO II units run $120–$180 in good condition; MB2e around $90–$130. The temperature accuracy and seal quality stay intact, and the parts (silicone pods, lids) are individually replaceable for under $20. Far better than a new no-name unit at the same price.
What about just buying dispensary edibles?+
If you live somewhere recreational is legal AND you batch fewer than 3 times a year AND dispensary prices are tolerable in your market, this is the honest answer. $5/serving dispensary gummies at 5 batches a year is $200; a machine is $250+. Below that cadence, the dispensary wins on math and the machine wins on hobby satisfaction — those are two different reasons to buy.
Does the calculator above weight things in a machine's favor?+
No — it's symmetrical. The $ recovered per batch formula uses the gap between manual and machine retention valued at your stated $/mg flower cost. If your flower is cheap or your retention gap is small, the machine takes longer to break even. The 'Show your work' toggle prints the equation.
What if I just want the machine because I want one?+
Then buy it — that's also a legitimate reason. This page exists to help people who are uncertain. If you're certain, the Machine Finder will pick the right one for your setup.
