I've bought quite a bit of kit from Calumet in the last couple of years, mainly online. The website is easy to use and navigate, I have no complaints with the prices or service as I rarely have any contact with a human being at Calumet and do my research online before purchasing anything. However, I purchased a battery pack for my speed lights last year and couldn't get it to work. After a fruitless phone call to the Calumet help desk it was suggested I take the battery to my nearest store where it could be checked for faults. After travelling to Manchester from Doncaster the fault was easily resolved (I should have also had batteries in my speedlights to complete the circuit) & something that I feel staff on the help desk should have known. It cost me a train ticket and half a day out of the studio to find this out, pretty annoying. The staff member in the store was very busy and not at all apologetic which made it more annoying.
