I bought this yarn winder because I have a job lot of cheap yarn which continually knots up into yarn squids which makes crocheting (and more importantly, keeping an even tension) really difficult.
So far, I have wound a yarn-end with success, and subsequently a full ball too. Both (problematic yarn balls) required me to sort out the yarn squids as I was winding, but it had minimal impact on the yarn cake that the winder produced.
Having crocheted with the small yarn-end cake, I have found that it makes working the yarn much smoother and a great deal easier.
