To be honest I am disappointed with this item. I ordered the 4.5 (special) interchangeable needles and whilst the service from This is Knit was speedy and efficient, in relation to the item itself, the left hand needle requires constant re attaching as it spontaneously unscrews itself. Very annoying.

Re my recent symfonie interchangeable needles review- well, this is embarrassing. Following my review, lovely Lisa was in contact with me and asked if I had used the key supplied with the needles to tighten the join. In a word, no, I hadn't! She also kindly sent a link to a you tube vid- simply explaining how to use the key to do it. I dug out the key (never used- duh!). Suffice it to say, the join in my needles hasn't budged since. Silly me. Thanks for your patience, Lisa and This Is Knit. You rock!
Thank you for letting us know about this issue Deirdre. That shouldn't be happening while you are using the tips, but thankfully these needles are fully guaranteed. We can arrange to send you replacement tips to get you back on track with your project straight away. I'll drop you a separate email now to arrange this.
