SENTRO 48-Needle Knitting Machine Review: Is This $50 Machine Worth It?
Yes, as a cheap way to try machine knitting, but not as a long-term workhorse. The SENTRO 48-Needle costs about $50, knits flat panels or round tubes with a hand crank and has a built-in row counter. Its plastic body and unpublished tube size are the trade-offs; frequent makers should look at the $157 addi Express Kingsize.
Our verdict
Buy the SENTRO 48-Needle if you want to try machine knitting for about $50 and plan a handful of hats, cowls or scarves as gifts. Skip it if you already know you will crank every week or want blanket panels, because the addi Express Kingsize publishes its sizes, ships with spare needles and table clamps, and is built for heavier use.
The listing describes a 48-needle circular machine with a hand crank, a row counter and a switch between flat and round knitting, made of plastic and described as suitable for ages 12 and up. It does not publish the tube size, the flat panel width, a recommended yarn weight or a warranty, and we could not find a SENTRO manufacturer spec page.
If the SENTRO wins you over, the natural next step is the Kingsize or the complete addi I Want It All set (about $410), which pairs the 46-needle and 22-needle machines with pattern books and replacement needles.

What can you make with a SENTRO knitting machine?
A hand-crank circular knitting machine moves yarn around a ring of latch needles each time you turn the handle. In round mode the SENTRO 48 makes a seamless tube; in flat mode it knits back and forth to make a panel. The listing pitches hats, scarves and socks, and those simple shapes are exactly where these machines shine.
What it cannot do matters just as much. Every stitch is plain stockinette. There is no ribbing, no cables, no lace and no shaping, so most finished pieces need hand work: gathering the top of a hat with a tapestry needle, seaming panels, weaving in ends and adding a pom-pom.
| Project | Good fit? | What to expect |
|---|---|---|
| Beanie hat | Yes | Crank a tube, gather one end, fold the other for a brim |
| Cowl or infinity scarf | Yes | A long tube, seamed into a loop |
| Long scarf | Yes | A tube pressed flat, or a flat panel |
| Blanket | In panels only | Many strips seamed together; slow on a plastic machine |
| Ribbed cuffs or cabled sweater | No | Needs hand knitting or a flatbed machine |
Our knitting machine guide explains the difference between hand-crank circular machines and flatbed machines, and knitting machine vs hand knitting helps if you are still deciding which way to make things.
Is the SENTRO 48 knitting machine good for beginners?
For a first taste of machine knitting, yes. The price is the biggest strength: at around $50 you can learn the rhythm of cranking, weighting the fabric and catching dropped stitches without a large outlay. The built-in row counter helps you make two leg warmers or a stack of blanket strips the same length, and the flat and round switch gives you both kinds of fabric from one machine.
The listing itself warns that the first round of yarn needs care and points you to the instructions. That cast-on round is where most beginners struggle, so expect a few practice starts. Once the yarn is running, a plain tube builds very quickly compared with knitting by hand, which is why these machines are popular for charity hats and holiday gifting season batches. Turning a crank also uses the arm rather than the fingers; our crafting with arthritis guide covers other ways to keep making comfortably.
What is the honest weakness of the SENTRO 48?
It is a plastic machine with thin published details. The listing gives no tube diameter, panel width, yarn weight range, spare parts list or warranty. The competing addi Express Kingsize publishes about 35 cm (13.8 in) in circular mode and about 45 cm (17.7 in) wide in flat mode, recommends yarn for US 6 to 11 needles, and addi states a 10-year warranty on its products. With the SENTRO you are planning projects by trial.
No spares are listed in the box. Latch needles are the part that wears or bends on any crank machine, and the addi includes 5 replacement needles. Before relying on a SENTRO for a big gift list, check that replacement needles are available for your exact model.
Do not motorize it. Owners share videos of drills fitted to the crank, but addi explicitly says its own machines are not suitable for electric screwdrivers or drills. A plastic machine is even less suited to that strain, and a spinning crank is a pinch hazard.
Crank and needle safety
Keep fingers, long hair and loose sleeves clear of the needle ring and crank while it turns, and keep the machine and its small parts away from children under the listed age of 12.
What do SENTRO knitting machine owners consistently report?
- Praise: a plain hat tube comes together fast once the yarn is threaded and running.
- Praise: the price makes it an easy first machine or gift for a teenager or crafter.
- Praise: the row counter makes matching pieces easier.
- Complaint: dropped stitches, especially during the first rounds and with thick, fuzzy or splitty yarn.
- Complaint: the cast-on round takes several attempts to learn.
- Complaint: needles or latches that bend or stop closing over time, with no spares in the box.
- Mixed: the machine needs holding steady or fixing to a table while cranking.
The pattern is delight at the speed mixed with frustration over durability. Owners who use smooth medium weight yarn, hang a light weight from the fabric and crank at an even pace tend to report the best results. Check the yarn weight chart before buying yarn for a machine project.
Sentro vs addi knitting machine: which should you buy?
Our Sentro vs addi comparison covers this in depth. In short, the SENTRO is the low-cost trial and the addi is the machine to buy once.
| Machine | Price | Needles | Published sizes | Spares included | Best reason to choose it |
|---|---|---|---|---|---|
| SENTRO 48-Needle | about $50 | 48 | Not published | Not listed | Cheapest way to try it |
| Sentro 22-Needle | about $26 | 22 | Not published | Not listed | Small tubes and kids projects |
| addi Express Pro 22 | about $96 | 22 | 4 to 6 in round, 6 to 8 in flat | Not listed in the specs we verified | Made in Germany, small items |
| addi Express Kingsize | about $157 | 46 | 13.8 in round, 17.7 in flat | 5 needles, 2 clamps, 4 feet | Frequent hats and panels |
| addi I Want It All Set | about $410 | 46 and 22 | Both machines above | 2 packs of needles | The complete addi kit |

What else do you need for a SENTRO knitting machine?
Plan a sturdy table edge and a way to hold the machine still, a supply of smooth yarn, and a few finishing tools:
- Smooth worsted acrylic such as Red Heart Super Saver 3-Pack (about $13) feeds more predictably than fuzzy or bulky yarn.
- A Knit Picks Ball Winder (about $20) turns skeins into center-pull cakes that feed freely.
- A Clover Pom-Pom Maker Set (about $14) for hat toppers.
For a machine-knit blanket, work out the total yardage first with the blanket yarn calculator, and buy every skein from one dye lot. Our beginner knitting setup lists the hand tools you will still want for finishing.
Who it suits
- Curious knitters and crocheters who want to try machine knitting for about $50
- Gift makers planning a few hats, cowls or scarves for the holiday gifting season
- Teenagers 12 and up with an adult nearby for the first cast-on
- Makers whose fingers tire of needles but who are happy to hand-finish pieces
Who should skip it

- Buyers who want published sizes, spares and a stated warranty in the box
- Anyone hoping to motorize the crank with a drill

Frequently asked questions
Is the SENTRO 48-needle knitting machine worth it?
It is worth about $50 as a trial. The SENTRO 48 knits flat panels and round tubes with a hand crank and has a row counter, so you can learn whether machine knitting suits you. It is plastic, lists no spare needles or warranty, and does not publish its sizes. If you already know you will use a machine often, the addi Kingsize is the better buy.
Sentro vs addi: which knitting machine is better?
For regular use, the addi Express Kingsize is better: it publishes 13.8 inch round and 17.7 inch flat sizes, includes 5 replacement needles and table clamps, and addi states a 10-year warranty. The SENTRO 48 costs about a third as much. Our Sentro vs addi comparison walks through every difference.
What yarn works best in a SENTRO knitting machine?
SENTRO does not publish a yarn range, so owners generally settle on smooth, light to medium weight yarn such as worsted acrylic. Very bulky, fuzzy or splitty yarns catch on the latches and cause dropped stitches. For comparison, addi recommends yarn meant for US 6 to 11 needles on its Kingsize machine. Test a few rounds before starting a big project.
Why does my SENTRO knitting machine keep dropping stitches?
The most common causes are yarn that is too thick or textured, cranking too fast, not enough downward pull on the fabric, and a bent needle or latch that no longer closes. Owners usually fix it by switching to smoother yarn, hanging a light weight or clip from the fabric, cranking evenly and checking each needle. The first rounds after casting on are the most fragile.
Can a SENTRO knitting machine make a blanket?
Yes, in strips. The SENTRO 48 knits panels or tubes that you seam together, and the row counter helps keep them the same length. It is a lot of cranking on a plastic machine, so many blanket makers prefer the sturdier addi Kingsize. Plan your yardage with the blanket yarn calculator before buying yarn.
Can you put a drill on a SENTRO knitting machine?
It is not recommended. Owners share drill modifications online, but the SENTRO listing only describes hand crank operation, and addi states that its own machines are not suitable for electric screwdrivers or drills. A motor puts extra strain on plastic gears and needles, can void any support, and creates a pinch hazard for fingers and hair. Crank by hand at an even pace.
