fast shipping. very friendly seller. he kept me updated on the shipping process and told me that he would send as 2 packages because of the magnets that could interfere. you need to drill a hole for the wire of the sensor. it uses one signal for rpm pulses and one signal for direction (5v fwd). the sensor works very well. however the torque voltage is dependent on temperature: at room temp it is 1.5V, outside (5 C) it is 1.85v at rest. so you need to set the zero point outside. recommended product and seller!
Even 90°degree angle extra was applied. Very good product!
