Very strong and secure parts storage

I use this organizer for a multitude of electrical parts. The top clear cover for small items and the bottom for larger. The top tabs hold the compartment lid very tight with not movement of contents from one bin to another. I like the latching method as it is really secure. The lower main compartment is also secure with the snap on latches holding the stiffer lid tight to the bottom bins. The whole unit seems when closed seems stiff and secure. This organizer seems like it is a lot more expensive than most others that I've looked at, but I haven't found anything stronger or having bins for both small and medium sized items. I will purchase another one of these again.
