Every time I use this set I congratulate myself for buying it. Instead of those piddly tubes you get at the hardware store, the ones whose caps get encrusted and whose tips jam up, I have a big selection in tubes having enough capacity for big jobs, and whose caps always work and whose tips never clog. Plus, the range of viscosities assures that I have the right type for whatever I'm doing. The only caveat I'd make is that these adhesives have a limited shelf life (2 years I think) and unless you're a heavy user, there's so much that you might end up throwing some out. I keep mine in the refrigerator to maximize its shelf life, but even if I don't get thru it all, I'll happily toss it and get another, because having it on hand is worth it to me. And it really isn't that expensive compared to the quantities you get in the piddly tubes.
