What reviewers say

SENTRO Knitting Machine 40 Needles Smart Weaving Loom Kit

Owners of 40-needle Sentro-style machines generally find them easy to set up and fun for hats, but report skipped stitches and jams with thin or fuzzy yarn.

Pros
  • Quick to learn for first-time users
  • Fast enough to finish a beanie in under an hour
  • Good value for the price
Cons
  • Needles can skip or drop stitches
  • Tension needs adjusting often
  • Plastic build feels light

addi Express Professional Knitting Machine

Owners rate it highly for speed and ease, especially for hats and circular tubes. Complaints center on the narrow knitting width and the need to anchor it firmly.

Pros
  • Very fast compared with hand knitting
  • Simple enough for beginners
  • Reliable stitch formation on DK and worsted yarns
Cons
  • Too narrow for large flat pieces
  • Moves around unless clamped down
  • Tension needs watching with thick yarn

Questions and answers

Which is better for making hats?
The SENTRO, for most adult hats. Its 40 needles knit a tube around 20cm across, while the addi's 22 needles make roughly 10 to 15cm, better suited to preemie or small hats.
Can the addi handle thicker yarn?
Yes. The addi takes 3.5mm to 8mm yarn, including super bulky. The SENTRO's listed range is 1.5mm to 3.5mm, with specs claiming up to 5mm, so thick yarns are risky on it.
Is the addi worth about $81 more?
If you want thicker yarn, a row counter and a sturdier German-made machine, yes. If you mainly want wide tubes cheaply, the SENTRO does that for $35.56 at Walmart as of November 4, 2026.
Which lasts longer?
The addi has the better reputation for durability: heavier build, made in Germany, spare needles included. The SENTRO is all plastic and has few ratings, so long-term wear is unproven.
Can either knit flat panels?
Both can. The SENTRO does flat weave up to about 26cm wide; the addi does 15 to 20cm. For blankets or wide panels, neither is ideal.
Which is easier for a beginner?
Both are hand-crank machines. The SENTRO ships with yarn and hooks, so you can start the day it arrives. The addi is simpler to maintain but you buy yarn separately.
