Review on Neewer 16''/40cm Carbon Fiber Camera Slider with 4 Bearings - Compatible with iPhone 13, Android Phones, and Mirrorless Cameras - Supports up to 2.2lbs/1kg by Jeff Islam

I was very impressed with the build quality of this slider, especially considering the affordable price. It glides super smooth. I feel like my friction slider might be a little easier to get consistently smooth shots just because it doesn't slide as easily. Roller gliders glide so easily that it can be difficult to maintain a constant speed. That being said I am very happy with the quality of this particular slider and have enjoyed everything I have received from Neweer so far.
