Feedback on these magnetic wrench holders

[86k10]

I just got a KRSC326 and wanted to put a magnetic wrench rack or two on the lid. I came across these and wanted to know if any of you guys use these.

Are they for laying down or will they work on a lid that opens and closes? Or am I correct in thinking that the only ones that work on the lid is the twist in type?

EDIT, I see that they are for horizontal. What ones do you recommend from actual experience?

This is the lid of my Harbor Freight service cart. Those two magnetic bars hold all the tools fine whether the lid is open or closed. The only thing is when the lid is closed I have to move the cart slowly because my garage floor is kind of rough and a couple tools can shake loose if I don't go slowly. Usually the big Wiha #3 Phillips. The wrenches actually hold really well even with the lid closed because they are held in the center where the weight is balanced.
