Review on Enhanced 4-in-1 Stabilizer Holder for DSLR, Mirrorless, Action Cameras, Camcorders, and Smartphones - We-media Youtube 📷 Vlog Low Position Video Rig Mount Suitable for GoPro, Sony, DJI OSMO ACTION, Nikon, Canon, iPhone, Samsung by Eric Rodriguez

The product is a camera grip. It's not a stabilizer. Why am I giving 5 stars? Because that's exactly what the manufacturer says - they say very clearly, no stabilizer, no batteries - and it's well made. I got caught in all the reviews that it helped stabilize the video. I think so if the reason for your shaky video is that you had to hold the camera/phone with two hands and now you can use one. But in the device itself there are no springs, shock absorbers or anything else - it is absolutely rigid. But a good pen nonetheless.
