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)

Easy to use and sturdy.

They weren't kidding when they said easy to install! All you do is pick where you want the base to be and stick it there with the adhesive side, then put the other side on your phone. The magnets are really strong and hold it well, not flimsy at all.

Wireless charging

I like it and it holds well when driving. The only limitation is wireless charges. Magnet gets hot or you have to remove your outer case.
