### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Works as advertised, very good value
  

*by J***E on Reviewed in the United States on January 13, 2020*

Price is one of the best I found.No instructions are included, however the pictures on  Amazon give a wiring diagram.. This is necessary because the "printing" on the case is almost too small to see.Plenty (actually more than enough) wire length is provided.Using this is quite valuable for me, the previous (from the factory) minimum speed was around 650 RPM, using this RPM indicator as a reference I was able to modify the speed drive to lower my minimum speed to near the 500 RPM I desired.  Also I was able to see how fast this machine would go if the max speed stop is bypassed.The display can be mounted in a "project box" for a more professional appearance. (The current installation is temporary, and I haven't done this yet).The photos show my "temporary" installation". Demonstrating the device works as advertised.  I assume it is accurate, although I do not have a standard to compare it to.  RPM indications (in photos) show the limits of the machine (normal speed controls overridden to achieve top attainable speed).One slight negative, the display does not give "instant" response.  Once speed changes  it takes about a second to update.  This isn't an issue but I felt obligated to point this fact out in the review.

    Nice product!
  

*by B***R on Reviewed in the United States on November 7, 2023*

I was not able to use the included Hall effect sensor due to space limitations, but I replaced it with a very small, flat one. Once wired, it works perfectly! This is a nice unit, and it makes my lathe much nicer.

    Wiring diagram needs improvement
  

*by I***Y on Reviewed in the United States on February 24, 2024*

This unit is easy to hook the sensor up. And easy to solder together. The tougher part is figuring out the wiring scenario. I use Google translate to help me with looking at the back of the LED module.1: + and brown wire of sensor2: ground3: blue sensor wire4: n/a5: black sensor wire12-24 volt power supply battery or transformer.The magnet provided will work, try flipping around and spinning on a drill to first check the sensor to determine what is the right direction. The South Pole is what the sensor will detect correctly.
