Review: EXCELENT PRODUCT - It's installed and does what it promises. It works very well.
Review: Nice module. inexpensive, easy to mount (snap in). - I bought this to show my lathe's speed. It worked well. A little problem mounting the magnet. Instructions say south pole. I used a magnetic navigational compass to determine north/south of the provided magnet. When I mounted south pole toward the sensor, it didn't work. Turned it around and it did. I epoxied the magnet so unmounting was a nuisance. Connection was simple, just be sure to follow instruction on wire colors. Ground yourself when handling electronics to keep static zero.
