Nope I did not get the effects I wanted. I only posted stats on how many rolls I've performed and offered a contrast of how many materials I've abandoned. Derailing that other thread with RNG complaints was inappropriate as the topic was specifically in regards to materials storage.
I have yet to get a single weapons modification that I actually want and am currently running around with a Thermal Shock, Thermal Vent beam laser combo despite the fact that what I actually want is a pair of Regenerative Sequence modified beam lasers. I've given up and am now simply waiting for the release of favors and spending my efforts exclusively on upgrading the modules on my ship that don't have chances for special effects that I don't want.
I've used enough materials to equivalent 40+ hours of gameplay on my rolls for weapon mods so far. I haven't mined for any of my materials thus far.
My biggest irritation more than anything is just seeing the roulette wheel land just right before, or just right after the lovely little box that grants a magical special effect. It happens 90% of the time on failures, easily. It's exactly like watching a fruit machine hit 77

and when every roll represents a bunch of your time... Let's just say I'm thankful favors is coming... I just hope picking also comes with a materials cost increase along with reputation costs. I'm very scared of what pure thermal shock builds are going to do in terms of meta.
