I've had Guarder clears work well for me, but their poor durability is a huge turn off for me. I've also found them to be extremely sensitive to different lubricant compositions.
Personally, I just want my guns to work when I need to use them. I don't want to be always worried about a part potentially failing, or a hop up rubber potentially being over swollen from too much silicone oil or whatever the case may be. I don't want to be always checking my rubber to see if it's torn, either (this goes for other activities *outside* of airsoft........)
Yeah, I ditch the cheap Taiwanese/Chinese made rubbers and stick to the trusted brands.
