I use scissor jacks all the time.... I used to keep two hydraulic bottle jacks in the boot (you need two to lift the car and change a wheel), but I've given-up on this due to the space it takes up in the boot. Every wheel I changed in the past 20 years was done with scissors jack... yes they are crappy but they are small, fold flat, and lightweight and ultimately do the job. What's the (practical) alternative? Unless you have a drive or garage and can use a proper trolly jack....
