|Image: The Sentro machine is on the left with a purple project in its center. The small, pink handle/crank has a ball on the end. The right side has the Addi machine with its handle prominent; it's larger with a thick, flat circle on the end to grab.|
The included tensioner you put on the machine (makes one-handed knitting easier)
Handle shape is smaller and easier for me to grasp
Suction cups on the legs (I can’t use a clamp on my tray, so they help the machine remain stationary)
The one thing I don't like about the Sentro is how, if you accidentally hit the reset button on the row counter, there is no way for you to go back.
P. S. The reason I started looking into the Sentro is because shortly after I bought my Addi the handle broke. The handle for the Addi set me back about 30 dollars, and it shipped from Germany. Also, a tensioner for my Addi costs eight dollars… I’m already on my second one.
