I have used this to service my car, it comes with a few handy accessories to make all sort of work possible. It does have 2 downsides though: 1) there is a dead space due to the syringe construction (there are holes in the piston), so if you use it for filling fluids, you need to add about 0.3-0.5 dl more as this amount is wasted (it would be nice if simple plastic plugs were available to plug this dead space).
2) The second downside is the quality of the winding at the syringe, mine came damaged and the head is angled about 10°.
In spite of the downsides, it really is an ok product.
