VERY SECURE. After inspecting the components, I decided it would be better to buy a cheaper universal kit. The combination of strap and magnet holds the meter securely to a flat vertical surface with a magnet. This is a very cool feature. I probably won't use any other components in the kit ie. Hook. The sales video at the bottom of the advert shows the tape and magnet wrapping around the pipe with the magnet attached to the back of the meter. It's an illusion. The magnet is strong enough to be attracted to the 9V battery inside the compartment, but not strong enough to hold the meter securely. All in all, I feel like I paid $30 too much for this kit. Since it's so overpriced I wouldn't recommend this kit to anyone looking for this but would recommend an all in one kit instead.
