Review Summary
2012-05-13T21:00:00
It is very well made with consistent results as each flash gives exactly what you expect. I use it in tandem with my Profoto D1's and am looking forward to using the Acute B2 in conjunction with my Elinchrom Quadra for some outdoor cycling shoots (as I currently only have one B2).
