Just ordered one myself...
Need to point out that the one sold by Pelican is OTC branded whereas the one sold through Walmart (by Tool Space) is Neiko branded. I'm more apt to trust a tool from OTC than the other brand, but for that price difference I'll take a chance. The photos of both testers look identical.
I don't really need a tester - I change my fluid every 2 years (or more frequently) regardless - but I just like tools.
