How durable is this? I am a graduate student in EE and math and break so many of the best mechanical pencils from staples and other office stores.

I am a Professional Engineer - Mechanical...I am always drawing diagrams and sketches...I am also a certified draftsman from the days when one was forced to draw professionally with a drafting pencil...This pencil will certainly meet or exceed your needs in engineering. It is durable and works well...only problem will be keeping other students from borrowing your pencil...permanently

I just love this one: the roulette has metal barrel; it is made in Japan. It is a little bit heavier the high grade ones. If you the person who prefers the lighter ones, do not buy those for $5-7 bucks (the color wears off and they scratch easily). I am accounting student; I use the metal one at home, and the lighter one (high grade) at university and at work. Both are durable and last forever. I use .5 lead diameter and I would NOT use .7. As you know the lead turns and the writing is even; love for the neat look. I abandoned other brands. Buy one for yourself and enjoy. (NOPE, they do not pay me to prize the product!)

I think it's one of the better models to have because it's not very heavy and has the rotating mechanism for the lead. In comparison to other pencils, it's more about the lead that determines breakage. This model has diamond infused lead which makes them a lot more resistant to breakage but good luck finding the replacements for it. If you're looking for good replacements, then get the super high polymer replacements from the office supply stores because they work just as well (if not better). They're also cheaper and easier to find.

I actually bought this mp to add to my mechanical pencil collection. I now have about eight mps, all different. Therefore, I could not provide any info regarding its durability. I can say that this is a beautiful, finely crafted instrument. It may be the best in terms of appearance. I really don't think you would go wrong if you selected this one. Best of luck!!

Has been pretty indestructible for me. I certainly don't use it every day, but using a once a week for a few months, it still seems like new. I expect to get many years of use from it.

I have not had to pursue that issue yet. My guess? Office Depot or Office Max or some other type of store that carries a decent supply of office equipment. Not the greatest answer, right?? It's the only answer I have since I haven't used up even the first pencil (used it a lot...still haven't had to go to another pencil in the set yet).

It is durable... to an extent. I've had the product for seven months and I can safely say that there are parts that can break. I would highly recommend that you first buy the Power Rangers Super Megaforce Morpher first. It's the American equivalent to the Mobirate but little more durable and made for younger kids. But if he still wants the Japanese Mobirate, I say go for it.

With care they will not break, but they will grind down very quickly so don't push it in for long periods. Sorry burst works best. On a side note, the art teacher at school doesn't allow the students to use colored pencils in this sharpener for that very reason. You will do fine.

Yes, I've had mine since July 2013, I use it on my desk at work to hold my cell phone. When I'm bored or thinking, I take my cell phone off it and twist in whatever shape I come up with, so I believe it is very durable.

It sharpened them beautifully. Unlike a battery operated one I had which lost power and groaned everytime I put pressure on it. It did blow up after 20 pencils but that may be due to the power difference in Australia I suspect! I am very sorry that I can no longer use it.

A very sharp point will break with a very heavy hand but otherwise I press pretty hard and the pencil does fine. I love 'em!

No, I just bought another pencil. The lead lasts a long time for me, fortunately!

My first PaperPro stapler broke after about a year. I went through the trouble of contacting the company and they sent me a new one which has been working ok for about 5 months now.

It is actually really sturdy. My now 4 year old has played with it for over a year and it shows no sign of damage. It works as a dry erase also. The is how we practice letters. I put the big and little letters on the board and she uses a dry erase marker to copy the magnet.

I have been removing it from my home & office desks twice a day, it has been durable sofar, but it has only been a week since I began using it. I'm also interested in knowing the long term durability.

We have used about 40 at all times in construction for over 4 years and have had no breakage except the belt clip which you can buy for about $5 from Amazon. The other problem is sometimes the rubber gasket will get loose but that is after couple of years or if you take it in and out of the hard cover a lot

Sorry I don't know but the extra long don't last long. I won't buy them again. I have one with an extra hard rubber tip, but I don't know where I bought. It will last forever. The rubber tip fit over the pencil.

This item is durable, but the grip was discoloured after too much use. This item is VERY easy to use. The dimensions are the same as a normal pencil.I truly recommend this item.

In my classroom, I got about 15 months of consistent pencil sharpening. I have looked for the replacement cutter so I didn't have to buy a whole new pencil sharpener, but I think I'm going to end up purchasing a replacement.

Durable? In what sense? I wouldn't drive over them with my car. The cartridges are well built and will endure the stresses of sitting on a shelf or in a drawer until they are installed in a printer. Once in a printer they are even more resilient, lasting until the ink inside has been exhausted and the cartridge disposed. The ink is of a high quality and will probably last as long as any other quality ink.
