Cheap and tough
I got this for a trailer not a truck and it works perfectly for dump runs instead of using a tarp and bungies. Comes in a little bag I'll never use again and had some accessories i don't understand, but if you want a springy net for something that's cheap enough not to care about breaking this is your product

Exceeds my expectations!!
Great product design, very versatile with an incredible magnetic. Worth its weight in gold. Works perfectly as described, actually surpasses my expectations. I sail and have placed this by my helm for my device, which I use for navigation and other purposes. Despite encountering severe weather conditions, it has never failed me. I’ll be ordering more of these in the future for my other devices and as gifts.

Hands-free video watching
Handy tool especially while I am working at this computer. I can work and watch a video at the same time. Tool holds it tight with a strong magnet. (Turned my phone around for the pic for privacy)
