Fast deliver, item arrived in 7 calendar days from date of order. No import taxes paid. Item appears exactly as described in the description. Item came well packaged - unopened, sealed in anti-static bag and in a Jiffy bag. Connection pins supplied which were easily soldered. I have checked the output from the unit using a solder less breadboard and Arduino Mega/Raspberry Pi 3B+ combined setup and all works well. You will need to download the PDF files for this product. There are also code samples

Small device, easy to operate it with an Arduino. Jumper pins are provided.

Nice sensor. Not the most accurate, but ok for hobby.
