The 0.7mm is my favorite...

The 0.7mm is my favorite size of Kuru Toga pencil. I found the 0.5mm a bit thin although my son likes the 0.5mm best. As with all Kuru Toga pencils the rotation mechanism works extremely well and is not distracting in the least. If you use a harder lead the line will be a bit lighter/thinner and a softer lead will be a bit wider/darker.

Too bad the eraser design sucks. You have to remove/lose the cap so I've never used it although the tiny eraser may erase just fine. This pencil is too darn good to lose stars for that but it would be a better pencil if it had an easy to use eraser with some bulk to it.

Like many mechanical pencils you have to throw away a lot of lead when you advance a new lead. There are some inexpensive pencils that use all the lead. The "Platinum OLEeNu Lead Breakage Prevention Mechanical Pencil" is available through Jetpens for 0.5mm and I remember seeing some real inexpensive ones for 0.7mm locally.
The rotating mechanism...

The rotating mechanism works wonderfully and I won't use a regular non rotating mechanism unless my Kuru Toga is not available. I have the 0.3mm and 0.5mm Kuru Toga (0.7mm on order) and they are all the best mechanical pencils I have used. I use the 0.3mm for fine work and the 0.5mm for regular work although I find the 0.5mm a touch fine (my son thinks the Kuru Toga 0.5mm is perfect).

The 0.5mm lead has about 3 times the volume of material than a 0.3mm lead and they last quite awhile before having to advance the lead. The Kuru Toga advances the lead a relatively short amount compared to some other mechanical pencils and that helps reduces breakage. The only time they break is when I don't let the lead wear right down before advancing.

Once the lead pushes past the advancing/rotating mechanism it is best to advance a new lead and throw away the rather long bit you just pushed through. I tried using up the non rotating lead by pushing it through from behind one click at a time but small pieces of the new lead kept breaking off inside and eventually jammed. I unscrewed the end to clean out the dozen or so bits that collected in the tip.

The 0.5mm Kuru Toga makes the slightly thinner line than a standard mechanical pencil, almost the same as a standard 0.3mm.

I don't bother using the eraser as you have to remove (and lose?) the cap. I guess it's okay for emergencies but I try to keep a standard eraser handy. Having spare leads included is a real bonus and they are strong and dark.
The turning mechanism...

The turning mechanism works wonderfully and keeps the line very fine. I only use the 0.3mm for small work as the lead wears fast (all 0.3mm leads wear fast, they have approx 1/3 the lead volume of a 0.5mm lead). For standard work I use the Kuru Toga 0.5mm or 0.7mm.
