The item was very small than i expected(around 2X1 inchs), and works well when checked with multi-meter. The package was good but an added small bubble wrap would have been better as the box in which the board was put was little large and it must have been bounced inside the box throughout the transit. But good product none the less.

Wonderful product. Build quality is also good. I am using it as as Mobile Charger for my 2 Wheeler. Its working perfectly. So I am going to order 1 more piece for my another project.

The product is good and the output voltage is very stable. I recently got this device and put to use.
Thinking of buying some more.
