Hello from Finland.
I noticed that one of our big department store chains (Hong-Kong) has really good looking aluminium car jacks for sale. They are really nice looking but the jack stands which come with the main jack are really dangerous. The bottom plate is so tiny that it is really unstable. It doesn't need much force to fall it down and if you are under the car this can be very dangerous. How do you feel? These jacks do not even have any CE-markings at all! This is Canadian make which makes this quite odd because I believe they must have some kind of safety regulations too.
