I've bought a few things and rented from Calumet a couple of time in the past before my most recent rental. I've always received very good advice and service from everyone I've dealt with. On this particular occasion there were a few issues (not helped by the fact that I'd made the booking last minute and certain equipment was understandably not available), the main one being that I took away a pair of PocketWizard Plus iii's rather than the Air Remote for the Profoto D1 strobe setup that made up part of my rental, and wasn't aware that HSS wasn't supported which affected the shoot. The other being a missing cable for the transceiver which forced a second trip to collect. I had a discussion about compatibility up front and whether I'm correct on this point or not I did feel like I should have been made aware that the pocket wizard/profoto D1 combo wouldn't allow me to shoot over 1/160th without the mirror blocking the sensor. I didn't mention HSS, but 1/160th being the fastest shutter speed achievable should probably have been mentioned. On raising my concerns with the communication issue I'd experienced, I was absolutely delighted with the way Mark from the rentals desk in Manchester handled the situation. I went from a calm state of quite pissed off, probably never to use Calumet again, to feeling like a highly valued customer in just a few minutes. You have a cracking employee on your hands there and he absolutely deserves recognition for it. Nice one Mark.
