A Beginner Friendly Way to Turn Scraps Into Amazing Garden Soil
If you like the idea of composting but hate the mess, smell, or effort that usually comes with it, you’re probably looking for something less messy than a backyard pile and cheaper than an electric composter.
And once you start composting, you’ll probably start looking for an excuse to stop and give up on the whole idea within the first month.
That’s where the Sun Joe SJ-CMPS1 Dual-Chamber Compost Tumbler fits in.
It’s one of the most popular budget tumbling composters out there. And after digging through real user reviews, it’s clear why. This bin isn’t flashy, but it solves the most common composting problems that cause people to quit.
Here’s what it does well, where it falls short, and who should (and shouldn’t) buy it.
Quick TL/DR Verdict
Best for:
- Beginners
- Home cooks with regular food scraps
- Folks with small to medium gardens
- Anyone who hates turning compost by hand
Skip it if:
- You want zero assembly
- You compost massive amounts of yard waste
- You expect premium hardware at a budget price
Bottom line:
If you want an affordable, low-mess way to compost faster without dealing with a huge pile of garbage in your yard, this is a good buy.
What You’re Actually Getting
The Sun Joe SJ-CMPS1 is a 42-gallon, dual-chamber compost tumbler designed for outdoor use year-round.
Here’s why that matters:
- Dual chambers let you keep adding scraps without stopping the composting process
- Tumbling design mixes compost just by spinning it
- Enclosed barrel helps control smell and keeps things neater than open bins
Instead of dumping everything into one container and waiting months, you rotate between chambers one active, one finishing.
That alone makes this much easier to stick with long-term.
How This Composter Performs in Real Life
Most owners say the same thing, and I agree: “once it’s built, it’s easy.”
You open the sliding door, add food scraps or yard waste, close it, and spin the drum a few turns every couple of days. No digging. No extra tools. No beating back a soggy compost pile with a shovel.
People switching from traditional bins or piles often say the tumbling action is the biggest upgrade. Mixing compost regularly speeds decomposition and prevents the wet, smelly mess that turns people off composting altogether.
The dual-chamber setup also gets a lot of praise. You don’t have to “pause” composting while waiting for a batch to finish which is one of the biggest reasons single-bin composters fail in real homes.
Why Buyers Choose This Over Cheaper Bins
There are a lot of budget composters. It’s a surprisingly crowded market, really. Many of them are little more than just plastic boxes when all is said and done. At this point, most people looking to start backyard composting are already “do-it-yourself” types and if they’re going to buy a composter that is basically just a big bin, there are more than enough home-made extra cheap options online.
This one stands out because it solves three pain points handily:
1. Less Smell
The enclosed chambers help contain odors when compost is balanced properly. Compared to open piles, this is a huge improvement. Looking nicer than a big pile is an added bonus.
2. Faster Results
Tumbling + airflow = faster breakdown, especially in warmer months. Making the tumble easier makes good results much more likely.
3. Less Effort
Spinning a barrel will beat shoveling compost every time. If you haven’t tried composting yet, trust me, mid-phase compost is one of the worst things you can get on your clothes.
The Downsides
No product is perfect, especially in the mid-budget range. The complaints across multiple sellers are rather consistent, yet manageable.
Assembly Takes Time
This is the #1 complaint, and I struggled here as well.
This compost tumbler comes completely unassembled. Expect to spend about 30–60 minutes to assemble, especially if you’re doing it solo. Once it’s together, though, it feels nice and sturdy.
Tip: Using a drill instead of hand tools makes a big difference, but you will need a few different bits.
Sliding Doors Don’t Feel High-End
The plastic sliding doors can stick a bit, especially when the chamber is very full. They work, just don’t expect premium hardware at this price.
Most users get used to it after a few uses, but it’s worth knowing upfront. I read in some reviews that a little grease/oil along the inner track helps this issue a bit, but it’s not a perfect fix.
This model shines if you:
- Cook at home and generate steady food scraps
- Want something cleaner than an open compost pile
- Have limited yard space or an HOA or neighbors who aren’t ok with an open pile
- Are composting for gardening, not large-scale yard cleanup. While it’s a handy and efficient composter, it’s not huge and can only hold so much.
It’s especially popular with first-time composters because it’s forgiving and easy to maintain once you understand the basics.
You may want to look at a different option if:
- You compost huge volumes of leaves or grass
- You want something fully assembled out of the box
- You need something completely animal-proof
- You don’t really generate a large enough volume of compostable waste
This is a household composter, not a farm-scale system.
Common Mistakes That Slow Things Down
Most “bad” composting experiences aren’t caused by the bin; they’re caused by inexperienced usage.
Here’s what trips people up:
- Overfilling a chamber makes turning the tumbler harder. This can take a while to get used to and figure out the right levels. So, be prepared for a bit of trial and error
- Too many food scraps, not enough dry material. Proper composting requires balanced input
- Forgetting to spin it regularly. Turn every 2 or 3 days. Put it on your calendar
- Expecting fast compost in freezing weather
If you balance “greens and browns” and give it a few spins a week, results are much better.
FAQs Buyers Ask Before Purchasing
Does this really compost faster than a regular bin?
Yes, especially in warm weather. Tumbling and airflow speed things up compared to passive bins.
Is it hard to turn when full?
It’s manageable, though it’s easier when chambers aren’t packed too tightly.
Does it smell?
Much less than open compost piles when used correctly.
Can animals get into it?
It’s secure, but you’ll want to avoid too many greasy foods and keeping it away from fences and trees to limit easy access to climbing animals. Critters can get creative when the compost smells tasty!
Is it good for beginners?
Yes! That’s one of its biggest strengths. Once it is put together, it is easy to use.
Can it stay outside year-round?
Absolutely. Composting slows in winter, but the bin holds up to weather.
Is the Sun Joe SJ-CMPS1 Worth the Money?
For most home gardeners and beginners, yes.
This composter isn’t fancy, it’s functional. For the price, it delivers on the things that matter: easier mixing, less smell, and a system people don’t give up on after a month.
If you’ve tried composting before and quit, this style of bin often makes the difference. And if you’re new to composting, it’s a practical place to start without over-investing.
