Review: More detailed information. - These things are great. So much quicker and less messy than measuring out each component. The pump delivery volume is not described very clearly and so can be misunderstood. Here are results of measurements I made on pumps I purchased. The large pump delivers about 0.66 fl. oz. of resin per full stroke. The 207/209 hardener pump delivers about 0.22 fl. oz. per full stroke; mixing this with the resin yields a total of about 0.88 fl. oz., with a resin to hardener volume ratio of about 2.95. The 205/206 pump delivers about 0.12 fl. oz. of hardener per full stroke; mixing this with the resin yields a total of about 0.78 fl. oz., with a resin to hardener volume ratio of about 5.45. With this information, you can figure how to use these pumps with other brands of epoxy.

What I now know is every person that gets their mix wrong (using West) NEEDS to get these pumps. I have one on my 207, one on my 205, and one on my 105. 207 requires a 1:3 ratio but with these pumps ... one pump of each is the exact ratio. And to make things better, you can just leave them on the cans (although I do a single purge pump of each before mixing a new batch). Very happy with West overall.
