I gave three stars because the concept behind this charger is very awesome. When you first plug it in, it glows these cool rainbow colors. After about 8-10 seconds though, it stops. I was under the impression that it's supposed to glow the whole time the phone is charging? I messaged customer service and they told me that it's supposed to glow the whole time the phone is charging. They didn't offer to send me a replacement or anything so, I'm assuming that means I'm stuck with a cord that only glows the first 8 or 10 seconds that it's plugged in. It sort of sucks but the magnetic chargers are the only ones I'll use from here on out. Just maybe they need to address the issue with the cord not glowing the whole time the phone is charging.
