The metal pipe tip is far more sensitive, and retracts out of the way for the lead itself much better than I expected. In essence, you ARE writing with just the tip of the lead, as if it were extended beyond the tip. It's the fact that it slides back so effortlessly, and so smoothly, that you really don't even notice it's there. Combine that with the auto lead advance system, that will push out just enough lead to match how much you just used every time, and I honestly never had to manually advance it even once.
Also, build quality is excellent. The body is a metal infused plastic, that feels premium in a way I've never really felt before. Not as heavy as solid steel, but not as lightweight as plastic. It's a great balance, and feels perfect to handle. I also never had a single lead breakage, so I can attest to the fact that it does work fully as intended.
This auto-advance pencil has a spring that constantly pushes out the sleeve and the lead. This constant pushing makes it somewhat scratchy. Not having to click to advance is a great feature.
I solved the problem by using B lead or 2B lead. Because the lead is softer, you don't have to use so much pressure. The reduced pressure reduced the scratchiness. Also, the scratchiness decreases with use. The people who use 0.2 lead pencils are not heavy-handed writers anyway - so I don't see it as a disadvantage.
I suggest the 0.2 mm version instead of the 0.3 mm version. The 0.2 lead is the type that needs advance more often so auto-advance really helps. I hardly advance my 0.7 mm pencil - the lead lasts a long time there and so there is less use for an auto-advance feature.
I think the price was worth it for the sake of experiencing the novelty of this invention, but maybe don't buy it expecting it to be the "ultimate pencil".
For one, the body of the pencil is a bit rigid-feeling, so it's not the most comfortable pencil to use. Also, the lead is on the lighter side, which makes it harder to see sometimes, so I may try to switch it out for a darker color lead.
You can push it down on a hard surface with the button pushed to retract the sleeve to protect the sleeve and your pocket. It also feels good in the hand and the clip is high enough not to touch my hand.
