I went with a Lomax this time around, coming from a Bak MX4 on my 2017. Very pleased with the quality of the Lomax. The ease of removal of the cover when needed is excellent. The appearance of the Lomax is shortchanged in many reviews and videos, it has a superior finish.
Regarding an earlier comment on being able to defeat lockable covers with a coat hanger; a simple block of wood or plastic, ¾” x 6” double side taped directly in front of the pull strings solves that easily. This applies to all foldable covers with releases like Lomax and Bak. A simple solution, I don’t know why manufacturers don’t do it themselves and advertise it as a higher security feature.
