Familiarity: I've used it several times
Firstly these things are great and I would recommend them to anyone. They are super low profile, extremely easy to install and have done everything I need.
The one gripe I have is the latch system is a bit funky. When the rack is full I can definitely never close it all the way and more often than not I can only get it to latch 2-3 down which makes me feel like it's going to open.
If I do push it too far down the locks won't turn and I can't lock the system.
So overall it works great, but you have to have a bit of trust that closing it with just 2 latches won't open :)
