I'd bet this launch does have an effect on a few of the retail partners reputations...
I doubt it. Although the whole Solo/gimbal drama as it's being played out is of big concern to most here (myself included!) surely it's a very miniscule portion of B&H's overall stats.
Whenever anyone bashes B&H on a forum typically dozens of it's defenders jump in to relate their positive experiences. Myself included as I've spent tens of thousands of dollars at B&H for companies over the years and spent more hours than I care to remember browsing around their NYC showroom. Aside from the very rare surly salesperson, I've nothing but good things to say about their operation.
If you've never been to their NY store and have the opportunity to go-- it's definitely a "must see".
