VIVOSUN Solar Irrigation System

Top

USB charging ports on all 3 units purchased had wrong polarity cables soldered to port unit. Consequently USB charging not functional. Positive(red cable) to circuit board soldered to GND(ground) terminal on port output. Had to resolder connections for correct polarity, which was easier than contacting vendor. Purchased units 4 months before needed and hadn't tested them on receipt. Fair to assume a fundamental error in wiring shouldn't have passed manufacturer quality control.

I would give less than 1 star if it was possible as product did not work at all. I do have a video review but because I didn't upload it straight away, as to give the device reasonable time to charge the internal battery via its supplied usb just in case if by chance it was completely flat, it was left to charge for over an hour and the display never lit up and/or never gave me any indication. I have already returned item so I only have a pre-recorded video review which amazon's app doesn't appear to agree with, so I am unable to leave a video review as everytime i attempt to upload it the app sends me back to the amazon main page away from review. I advise not purchasing this item as I was not convinced there was any internal hardware in the item as it was so lightweight. I did not attempt to open it as to avoid voiding return. I was surprised at the poor, unresponsive quality as I have purchased a vivosun product in the past which had turned out to be of great quality and standard, so i am very disappointed with this product.
