I have several tubes. Originally got AS5 when I did builds, and then had gotten a couple tubes of TX2 that came with some CPU coolers when I did builds for a couple people.
Until I bought my first tiny tube of AS5 back in like 2007 I strictly used the white goop that was offered way back in the day. I had so many of those and finally ran out. I have a huge tube of AS5 that came with the computer I bought off CL and still have that little bitty one that I bought in 2007. Damn **** cost me $15!
