Hi - fairly simple question I hope, I need to replace the blades on my Yeti and there are two types of the Bosch ones available - AM24U which have aMulti-Connector Fit and A980S which has a push button fit and is much cheaper. What ever happened to the old fittings?? Any advice would be greatly appreciated as I have to buy these on line to save around 50%

According to Bosch you should be using the A980S ones.

See this thread, amongst several others in the Yeti section.:
