A follow-up

I started a dishcloth with the bamboo needles.
The main difference I have noticed is the sound. I've never been a fan of aluminum needles clinking together. The bamboo needles make a soft "swish" sound as the yarn slides along them. The yarn also slides along the needle more easily. The best part of these needles is their short length. They're 9 inches. Which is something I'm sure I could have found in nearly any material.
Overall, I'm not giving them rave reviews like most others have. If two sets of needles, identical in every other respect, were placed in front of me, I would choose the bamboo over an other material. But, I'm not about to replace all my needles with bamboo.
