CanaKit Raspberry Pi 3 B+ Starter Kit

The Raspberry Pi itself (which I assume Canakit did not manufacture but gets from an authorized manufacturer) works great so far. But the items in the kit that are CanaKit-branded really suck: - The power supply. Under a Pi stress test (not overclocked; fully within the RPi's operating limits), the Pi claims 'undervoltage' when running at 100% cpu. Note this is not a fault with the Pi. When I use the Official Raspberry Pi Foundation 5V 2.5A Power Supply WHITE instead, it works FINE, for long periods of time doing intensive computation. The Canakit power supply caused undervoltage in just 10 minutes of intense computation. - The microSD card USB reader. I used it a total of 3 times before it failed. When I tried to use it in the Pi to try to clone my disk, the reader failed. 2 different SD cards in 2 different computers cannot be read anymore by this microSD card reader. And those cards and computers work just fine with other readers. Note the SD card itself (Samsung) works great. Only the CanaKit branded item failed. This is already my second order. The first had to be returned & refunded because it had liquid stains on the (supposedly new!) plastic case. I'm not returning this one (yet) even with the poor quality items because I don't want to waste the time setting up another Pi. Sigh. With my second Pi, I bought the items separately, without a kit. When you pay for quality individual items, it works much better than this 'kit'.
