Depends what you want them for. If it is to drop the car on the floor with as little money as possible they are fine! They are what they are, build quality, ok, performance, ok. imo for £160 they are a steal! I have had cheap coilovers on my scirocco for around 3 years and they work fine. Rock solid mind. I have less than 1cm between tyre and arch and they don't rub!
If you want excellent handling, feel, and quality then no...
I know i will be buying some for my a3 soon as i simply want it to go low low low.
