I will start off by saying that I did receive this product for free, in exchange for writing a review. But my reviews are honest, and never influenced by receiving the product for free. I've had problems charging my phone on previous trips, because I clearly wasn't using the appropriate converter. When I opened this product, I really had to read the instructions to feel confident that this product was good for my Samsung Galaxy S7, as well as to charge my Fitbit, wireless headphones, iPod and camera. I ended up keeping the cardboard label from the packaging with this converter, to remind me what the product is good for, and what it's not good for. This product definitely did what it's intended to do. Charge my phone and other smaller electronics (not my super duper hair dryer). My only complaint is that for the price, it should come with a better bag or something to store it in. The fabric bag it comes with is too small, and all of the pieces fall out if you try to use this for storage. Get something to store this in.
