Most of those are just junk. For one thing the bubble doesn't fit well between the lines and you end up having to guess when it does.Amazon 2 pack for $8.
I like this particular model, but you have to set it up on the scope so that the bubble shows level when the vertical crosshair is vertical. You can do this by setting the scope in 2 V noches cut into the bottom of the scope box. Orient the scope so that the vertical crosshair is aligned with a straight edge on a building.
There is also this useful little item which attaches to a Pic base and can be handy for making sure that your rifle itself is level, esp. if you use a Harris or other bipod.
I have a Pic base with a built in level, but it is also near useless since it's hard to see and the bubble is a poor fit between the lines.
