There were two NS indications in reverse. Although it is a simple experiment, there is no particular problem, but in reality it is desirable that everything is correct.

It is very easy to use because it does not take up places to see easily.

When using the in-hole camera vertically, I tried to install it so that it knows the direction, I bought it. Although I have not installed yet, I think that the movement is smooth, low cost, although it is not an oil type.

It's cheap. The goods are neither good nor bad. it is normal.

It is very small, but it plays a role of a compass needle firmly. It is wonderful to purchase this quantity 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.
Mountain walking and more

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.
