I didn't purchase this exact tool from Amazon but purchased a very similar one from my local auto parts store (because I couldn't wait for shipping) and all I have to say is this is the ONLY tool that would take off my stuck oil filter. The dealership torqued my filter on so tight that I ended up trying 8 different ways to remove it (BOA constrictor style, channel locks, standard oil filter strap style wrench, socket style, even the "screwdriver through the side of the filter" trick). I spent almost 4 hours working on it with other tools and once I got this it literally took a matter of seconds to remove it. One of the main reasons the other methods didn't work was due to the location of my filter (under the exhaust manifold and beside an engine mount) so it was very difficult to get to from the side with any tools. If you have access to the end of the filter and have room for a ratchet to move then this is the tool you need (especially if you have a stuck oil filter!!)
