Last year purchased a Bartech Wireless FF with hopes that it would be rented out with the MOVI, but most of my clients wanted one man majestic. So, I took a loss and sold the mint new Bartech kit. Now, I need the WFF option again. Are there cheaper options that you would recommend? Has any one used the Ikan Remote Air One (PD Movie) Single Channel Wireless Follow Focus System with Standard Torque Moto ? Report please. Redrock Micro seems to get a fair amount of negative and positive? When I first started shopping, the reviews were about 50/50 pass /fail. Has it been improved? Thanks for your response! Sean
