Stable that was all!

The advertising and the price had enticed me to buy the product. Unfortunately, the product my expectations not met. The compass showed only hesitantly, if at all to the right direction. Turned to the compass and then wanted to get again shown the previous direction, but one was disappointed. Because the unfortunately was not. Such a thing can not be reliably. I already know in advance the direction, I do not need more compass. Will I know the direction in unknown terrain, I want to be able to rely on the result of the compass. This was not the case here. Therefore, I have the compass also sent back.
