RPG - which products have you used?

I'm interested in three of the different RPG bass management products, the modex corner, the modex plate, and the modex panels. Anyone try these, and care to share their experience specifically with regards to how many you purchased, how you've used them, how many of them were required to fix your bass issue, etc?
