good idea. lead needs to be stronger. when it breaks it really doesnt go to waste, but could stand to be stronger

Yeah there are some design problems here. I ordered the plastic holder and 4 sets of leads in different colors based on the rave reviews for the basic holder. Well after getting it I dropped the pencil once and broke the lead into multiple pieces... not a bad drop, just off my work surface. I put in a new lead strip and voila, dropped it again. Lead shattered again.
What doesn't show well in the picture is that the leads have grooves in the back side which weaken it considerably.
As mentioned in the other review, the large square tip is great if you're trying to make a large mark, but if you want to make a precise mark you need to make the lead stick out farther and tilt it onto a corner. That makes it hard to line up with a line on your yardstick or tape.
...Unless of course you want to sharpen it, which was the thing I was trying to get away from by purchasing this pencil.
Good idea, but needs more improving.
Stick with your quality carpenter's pencils that you can sharpen with a machine, your pocket knife or your sander (my choice).
Oh, and those rave reviews? I always get suspicious of multiple perfect reviews of a product when all of those reviewers have only ONE review... makes you stop and think, why would these guys make this product their one rave review when it's actually not that spectacular.

Its really just another pencil that is made out of plastic. The tip is square until you sharpen it and still its not that easy to correctly sharpen it. Its not all bad though. I just don't think you are missing too much. 3 stars. Another words I went back to using the regular pencils. Might want to just try it though if its for you. I seem not too inclined.
