I am using these needles to knit my third cable-knit afghan in the past 10 months. These needles are smooth, fast, feel great, and are far superior to the less expensive bamboo needles I used for the first 1-1/2 afghans (and which ended up coming apart). I knit much faster with these needles. They are well worth the extra initial cost. (And how can you go wrong with a lifetime guarantee?)
I just love them they are the best needles out there !
Addi Turbo needles are what got me hooked on knitting. They are worth the extra cost because they are so smooth to use, the cable doesn't tangle or fight the knitting process and the yarn doesn't hang up at the connection between needle and cable. Truly a delight to use.
Using the correct length of circular needle for your project aids dramatically the ease with which the project progresses. If the needles are not the correct length you are forced to constantly adjust the knitting on the needles as you proceed. This really reduces the speed and enjoyment of the knitting activity.
