Review on Anmbest Bi Directional Converter Electronic Development by Tim Beckett

I bought this product for down conversion. 5 volts to 4.85. 5 per pack are all the same. I will never buy from this manufacturer again. Update: The company seems to be very proactive about their products, which is a great trait for a company to buy from. They contacted me and refunded the money for the purchase. I didn't ask for it and didn't expect it. I am updating my review because they have shown a great initiative in addressing consumer issues. Thank you Anmbest for your proactive approach and I will be buying from you again in the future.
