i bought their USB cables off amazon. they are like $18 when competition are $7 for 3. after 6 months they got loose. I can only charge my devices if i wrap it under the phone. and even then it is not guaranteed to work. I wrote a 2 star review, since it was 7x the price and failed within a year. They contacted me in less than a week, send me replacement cables of much better quality (they even had a cloth pouch!) and then kept spamming me to give them more stars at amazon. Which i did. One. And waited another 6months to see if the same happened. It did. So while i guess they do hit hard on support, i don't think they want to improve their products.
