I can’t give a full review as a highly experienced Ktip installer as this method is new to me but my initial impression is that it’s too big. I was originally going for the smaller tool but saw this said new and improved so thought it might be better. Tool works great- feels good in my hand- one side heating is great- lots of good stuff I’m sure. My negative is the arch in the rod gets too close to the head (and that’s the heat side for me) and well that can cause issues. I had to lift my elbow higher to make sure it didn’t touch. Only used it twice now - I wish I had gone with the smaller size but this is still a good tool and it did what it was supposed to do!
