I learned this the hard way — monetarily speaking, of course. Buy the absolutely most expensive circular needles that you can afford — even if it’s only one pair at a time. I have been buying mine sometimes using the inexpensive needles and other times buying the most expensive needles. Pay attention here…..
THE LESS EXPENSIVE NEEDLES WILL NOT HOLD UP!!!
I just finished a pair of socks with less expensive needles, and the tips are all pitted and do not slide smoothly. Needless to say, I have already bitten the bullet and bought another pair that are the most expensive. Don’t waste your money on cheaper ones. You can buy Addi Turbos on ebay at a decent price. You really do get what you pay for.
