## Customer Reviews

### ⭐⭐ 







  
  
    Didn't Work
  

*by S***E on Reviewed in the United States 🇺🇸 on September 7, 2016*

Bottom line, it didn't work in my application. I'm not sure if I got a defective unit. I looked at the remote end output with a scope and the signal was incredibly noisy as compared to the input. The bus I was extending was 100 ft of CAT-5 with my I2C bus running at 100 kHz. Clearly within the claimed capability of the device. Simple questions posted on the support forum went unanswered. I didn't pursue this further as a solution so I can't speak to what the problem was. I solved the problem by putting an inexpensive processor (Arduino UNO) near the location where the I2C sensor needed to be and wrote code to return the result via a serial port. I think this was ultimately a better solution anyway.

### ⭐⭐⭐⭐⭐ 







  
  
    Good option for use of remote I2C devices
  

*by D***1 on Reviewed in the United States 🇺🇸 on November 5, 2016*

The parts arrived as promised and worked perfect when installed. Study the documentation carefully and you will be able to utilize the devices to their full potential. I have not tested the devices with more than 100ft of cable .

### ⭐⭐⭐⭐⭐ 







  
  
    Five Stars
  

*by A***H on Reviewed in the United States 🇺🇸 on February 11, 2016*

I bought this to connect a digital temp/humidity sensor to a long cable.  Works as advertised. No problems.
