Honestly wont purchase there again. Health and safety appears to be rife. It could be seen that many of the staff were willing to place themselves in danger , exiting through into the warehouse without donning a high visibility vest or steel toe boots? This is very unusually as all drivers appeared to wear them , but the internal office appeared not to require them? ..... The part i purchased appeared to have a number scratched out on the side of the sensor , and came loose without a plastic bag?! I questioned whether this part i had purchased was actually new?! The person who served me appeared to have a peronality disorder and was more concerned about breathing his lunch he had that day all over me! I also found that many other customers were prioritised ahead of my self..... i can honestly say the place appears to be a hazard trap waiting to happen , with health and safety policies clearly not being followed. GSF really should follow this up , as i believe this is an unacceptable working environmement. As for my part that didnt work , i will not be using GSF again. Kind regards
