NS see something of the reverse there were two. It is the correct really all is desirable but is no particular problem because a simple experiment.

Because it does not even take legible location, it is very easy to use.

If you use it down the hole in the camera vertically, I attempt to install the tip so you know the direction, was purchased.
Although not yet installed, the movement but not the oil type is smooth, I think that good low cost.

I very small, but it plays the role of the firm compass. It is great to be able to this number buy at this price. It was very helpful.
Experiment on demonstration in class

Since anything is small and inexpensive, it is unlikely that many magnets can be experimented. Even experimenting with difficult magnetic dipole correlation can be done. After all, 30 pieces were purchased, but 1 piece, reverse polarity was found. Rather, it was very, educational. Depending on the ingenuity, we may be able to experiment with various state-of-the-art physics. It is recommended for all faculty members.

This price is very satisfying with 10 pieces. But, it is too small a little? It seems to be able to bring as much as we can to mountain walking and tooling equipment without worrying about loss.
