Based on my experience I found this oil tool to be quite disappointing and not worth the money .While it was made of durable aluminum alloy, the design was flawed and made it difficult to use properly. Unfortunately, the only positive thing about this product was its durability. The con, on the other hand, was that it didn`t perform its intended function effectively. Overall, I would not RECOMMEND this product to anyone in need of a reliable oil tool for their car..See full review
