I have the PELA 6000, which is exactly the same thing as this unit. I bought it a year ago off Amazon (my favorite store) just after I bought my used BMW 325ci. I read the reviews and simply took a chance. This thing has totally transformed what was an ugly, messy, and somewhat dangerous procedure, and transformed it into a fun project that takes less time than crawling under the car and fooling with a drain plug and unbelievably messy catch basin. You can do this in your street clothes, but do wear rubber gloves. You need to change oil while the engine is hot so the oil will flow quickly. The black dipstick tube is heat resistant and will not collapse from the heat. Keep in mind that the vacuum is not sufficient to pull cold oil out of the engine, so, only use this if the engine is hot.
