Im a professional mechanic who uses this tool often to fill transmissions with fluid.( no dipstick on german cars) Ive never used it for evacuating fluid but always to fill and it works very well. One grip i have with it is if you push the rubber plug into the top fully its murder to remove later to drain the fluid out.also there should be a drain plug on the bottom, instead of having to turn the thing upside down to drain.it leaks a little around the top and bottom screws, but i have yet in 11 years of being a mechanic found a fluid filling device that did not leak or create a huge mess while using it.overall this is recommended
