After being on hold for long periods, I did receive another power supply and controller. It worked for a few days and then I had the same problem all over again. I have not contacted them again - dreading the wait time. How much would you trust a company that replaces defective parts with defective parts?
Thanks for mentioning exceptions. I've found that Stephen Grider's courses on Udemy are outstanding. He's clearly found his calling in life. (I don't know him personally - have just taken many of his classes).
I was recommended Stephen from a colleague and now I've also enjoyed Stephen Grider's courses. I also really like them and his style! So far I've only done Vue JS essentials and Complete React Native. If I could be selfish for a moment I wish he would do at least one more Vue course with some more advanced concepts and tackling managing a large project with Vue.
