The size is just right. The strength of the magnet is strong, and it can be used as a pickup tool when dropping a nut etc. in a narrow place. There is a fall prevention cord attached, but do not use it because it is bad workability as it is attached. Please remove the code from the set and lower the price. It is a third repeat this time because it loses well on site.
Because my palm is big, 7.5 m fits comfortably and it is easy to grasp. I could choose 5.5 m, but it was inconvenient to think that it was short anyhow. 7.5 m is exquisite length for myself. Because it is a heavy burden to carry it on your waist, it will not fit over your palm any more, so this size has been changed every other year for about 7 years. But the wire that is stretched is a bit shorter, but easy to use.
