Do you prefer a mobile bucky stand or a fixed bucky stand?

Today, a customer from Guizhou inquired about the bucky stand, which is one of the best sellers of our company . The bucky stands are fixed and mobile. Fixed film racks can be nailed to the ground, people have to get into that filming is done in the room. There are four small wheels on the moving camera, which can move back and forth between rooms. As far as sales are concerned, it is better to buy mobile. First, because it is mobile, and second, because it does not need to nail on the ground.

Which type do you prefer?
