They are the immediate predecessor to the Esprit line and are very similar. AFAIK they are almost identical.
I use Bowens and have been very happy with them. Very solid units with complete reliability. The S mount for modifiers is very good as there is an astronomical amount of stuff available for it online as the Chinese have adopted it as a de facto open standard.
The fact that they seem to come with reflectors for the umbrellas is good as those reflectors are significantly more expensive than the regular ones.
Good product it seems. Fair price. Not screaming deal you may be able to get a bit better.
