Tianhao mechanical pencil

At the last visit at the local supermarket, I saw this mechanical pencil somewhat copying the design of the Pentel Graphgear 500, that came along with a pack of 20 2B leads, all for 0.50 $. If interested you can see some more look-alikes in the post Copy cats.

My thoughts were, I can not go wrong with the package, if the mechanical pencil is crap, at least I get an almost free pack of leads.

The design of the mechanical pencil is interesting, I would call it nice. I like the fact that the grip is a separate piece of plastic with a silver color while the barrel is black.

The mechanical pencil looks ok with the condition you look from a distance. At a closer glance, you see the pencil has a bend in the shaft. The fixed sleeve is a little larger than the diameter of the lead so there is play in the lead, and this causes the lead to break a lot. Also, the lead advances too much at every push. In combination with the soft, easy to break leads it came with it is a disaster to write.
But I found later why the sleeve is so larger, maybe ...
The led it came with branded as microled even though is 0.5 mm it is larger, or at least some of the mines are. I tested various leads in the post "Mechanical pencil lead", including the one that came with this pencil to see if is there a real difference in quality between known brands that have decent quality products and cheap no name leads. Biiiig mistake. I used a Rotring Tikky and first the lead broke. Not a tragedy but it got stuck in the sleeve and I could not get it out. It was stuck like glue in. I had to use a needle and pliers to push the led out. After a bit of struggle, it came out with a plastic bit that is inside the sleeve of the Rotring Tikky which has the role to keep the lead tight with no wobble when you write.
It does not come with an eraser, but this is not a problem for me as I do not like to use the erasers that come with my pencils. Not because they are not capable, but because I do not like the look after use. I always have an eraser block with me.
The clip rotates around the barrel and does not inspire confidence. But I think this is the greatest feature of the mechanical pencil. At least you can have the hope of losing it sooner rather than later. But probably this will not happen as the clip is not that problematic.

In conclusion, the mechanical pencil is bad and it's not usable.
