amazing this product seems like a good idea this works great just sucked out 5 qts out of my ski awesome used it once to remove the oil filter on my great filter tool best loosens well but doesnt tighten at all excellent requires work for the old vw crowd really like it worked great used in seadoo ski yamaha outboard complete failure so far so good nothing problem exceptional performance easy and efficient way to change oil in a car or boat five stars it worked perfect from now on i will use this to great worker five stars saved me a lot of time and effort
