For me it's a great tool,i have managed to strip hundreds of metres of 4 mm 6 mm cable,even 10 mm. Who says it's not good doesn't know to use it. It's still going good after all this use,cables needs to be straight amd the blade doesn't need to touch the copper. Only disappointed because doesn't have replaceble blades jist in case it's snapping,if you treat good lasts a good while
