Res filler cap

Why do companies make the filler caps out of such a piece of plastic garbage? The slots aren't deep enough to get a decent bite with a screwdriver and you end up ruining it by gouging out the plastic slot. I have one of the aluminum ones coming from Frozen CPU. Hopefully problem solved.

I have a dangerden one and it's high quality.

i had the same prob too, now im looking for a replacement, i was using tape for a while
