Bought for oil changes and whatnot.  Mine actually worked decent most of the time.  It did not leak from the side cap like many reviewers said.  My problem is that every couple months, while in storage, that side cap would split.  Thanks goodness I did not have oil in it.  Anyway, I emailed the mfr. (Blitz) from their website.  I never heard back in terms of a response but a couple weeks later I got three new caps in the mail.  I thought that was nice of them.  Unfortunately, it's been a year and all three caps have since split so I threw the thing out.  Would not recommend this product.
