five stars mityvac works great if youre careful if it was straighter it might not curl up in the oil pan as easily unless you are really anal it really doesnt works really well first vacuum pump i have used four stars love it very good quality and oil does not come into contact cant believe i didnt have this before my favorite filter removal tool universal oil filter wrench should work on any spin on filet but makes changing oil filters a breeze nice for cars but be careful if you want to use it on a cruiser motorbike great piece easy oil changes one star
