These are really good quality for the price. I bought them in hopes that they would charge my switch (the original charger my switch came with is too bulky for the case that I bought so I decided to buy this.) and my phone. they are made really really well, the cord seems good quality and hopefully won't be breaking within a couple months, they'll most likely last a couple years or more. I cant say if they're good for transferring information to other devices because I didnt buy it with that intention. overall very pleased
