These things are brilliant and my chests of drawers are so much tidier. The other ladies were right re: the problems of bras. These things won't hold them well, especially if you favour the underwired or padded variety. Having said this, Lakeland do stock half a dozen other such storage drawer devices in wood and plastic and what I've done is use a combination of these to find my own collection of ideal storage methods for the furniture and space I have.
These things are great for socks, pants, belts and ties, you could even use the smaller version to divide up a makeup drawer, but use something else for your bras, basques, and your 'giant scary stomach holding in pants'.
