Although I have no direct comparison, I guess the more expensive sets are much better handled. I bought the set for the first entry and to practice a bit with off-camera flash. The first impression and smell the flash holder made me my favorable purchase though only regret anything, but now I am quite happy and it does to practice its purpose without having to invest the same amount of money.
Those who work with customers or is dependent on time and reliability, should grab evtl.zu another set.
