One of the main reasons that I do not use head cement is that I hate the hassle it entails. Drying out, hard to apply at times, nastiness in general.
I have started seeing this lately and it's gotten me to wondering if it's a worthwhile investment? How does it travel? How does it hold up? Does it keep cement longer than the classic jar and needle dispenser set up?

So far have found no online reviews so thought I'd survey the crowd here.
