I bought this product for the engine in my boat. The space in the engine room is very limited and most people would have a hard time reaching the oil filter let alone the oil drain plug. On a boat, you normally have to suck the oil out through a special dip stick on marine engines. The only way to get to the oil drain plug was to remove the engine from the boat. This product allows you to drain the oil from the bottom of the pan. Since I didn't pull out my engine, I have only installed the filter relocation adapter for the moment. If you usually change your own oil, you will have no problem installing this product. It was much simpler to install than I expected. The price is very reasonable when compared to similar products on the market without sacrificing quality.
