AnonymousAir pump 5V - 12VComplies with the description. Still need to install the pumps, but they work properly (even at 3 volts)
Anonymous5V / 12V Waterpump 240L/HWorks perfectly on 12 volts, I couldn't get it to work with 5 volts. The packaging also only says 12 volts, so that may be an error in the description. A good service!
Tim de BoerFEETECH Standard Servo FS5106BGood servo for the price. The 2 ball bearings ensure smooth movements and the included hardware is a plus. Performs well on 6V. Satisfied with the purchase.
