The perfect assistant for removing the bobbin case from front loading machines. If you have the John Watts Perfection or the John Watts 1601PJW, this little tool is invaluable, as the bobbin case is situated a long way in from the opening of the machine. The EZbob acts as an extension of your finger, hooking onto the latch enabling you to remove it. The best $20 you will ever spend. Great for arthritis sufferers.
