I ordered the Hiya Hiya interchangeable needles ages and ages ago. They finally arrived on Monday. I love the flexibility of the cables and it's really easy to screw on the tips. No key is needed. Now to test them out with some yarn. I'll probably do that this weekend when I have some time since I won't be going to the Purl this weekend.
I love the case so much I want to get another one in blue and use it for my Addi Clicks. I hate the case from the Clicks and this has two rows for needles so it will be perfect. A different colour and I'll know which needles are in which case.
