Just received one of the new 1'X3' Profoto RFI strip boxes and can report they are quite nicely made in the typical Profoto manner.
I have all the bigger Profoto stuff, but wanted a few smaller strip boxes for both portable location and table-top work.
Once the 1'X3' arrived and I saw they were well made, I immediately ordered the $199 1' X 4' version with the 50º grid (which at $99 is actually affordable ).
I also ordered 2 of the RFI speed-rings for Profoto mount ... which are also less expensive than the standard ones. There are rings for most brands of lights.
Got them on Amazon which has them in stock where B&H did not.
There is a current promo running that gets you a Canon/Nikon RFI speed-ring if you buy all 3 parts (box, grid, strobe speed-ring) ... a $100 value. Ends Dec. 31st.
