Indispensable for "half-size" modules that are to be used in a "full-size" slot, in my case a "Intel Dual Band Wireless AC 7260" in an aged Lenovo T60p. The only problem was with me for a little too long screws, with which the plate is screwed to the wireless module: The screws put on an underlying component on (I think it was the module frame itself). Fortunately, I still had a couple of shorter screws in my stash, which the module then fitted collision. The manufacturer should make improvements, and attach two shorter screws.
