Review on Comimark Weighing Dual Channel Precision Pressure by Aaron Masek

The item arrived quickly and was well packaged. The chip used, HX411, has 2 sample rates and the description says they can be selected, but there was no documentation on how to do that. It's a very small board with very small letters on it. This is good in itself, but I had to use a strong magnifying glass to find the position of the jumper to change the sample rate. To change the sample rate I had to unsolder a very small component and solder it to other pads. It requires very good eyesight and a very steady hand. It took some effort, but I was successful. The product works as advertised and I'm happy with it, but if you're not comfortable with surface mount components and don't know how to solder, don't buy this product. There are other versions of the HX711 PCB that are easier to use but more expensive.
