Do you need these? No! When IT breaks on G you can repair it in 2 out of 10 times. Therefore one might think it is a good idea to prepare some spools before a show! But it’s actually pretty bad cause you lose meters of thread and money every time. These spools are not as professional and elaborated as Mesikas. They have no stop function, they are not concave or optimized. The plastic used is inappropriate and too slippery.
The IT gets loose by itself, which results in more tangled up thread and breakage. Beside the poor quality it’s heavily overpriced. These spools are not even worth 10$!
