Great light! Easy to use after setup. There was a small issue setting up the phone connection part as it wasn't included in the instructions, but it's pretty obvious. The part that fits in the ring light to hold the phone is slightly snug. Just be careful when inserting. If you have trouble screwing this fastener onto the phone holder, make sure the screw threads on the inside are loose. I had plastic trash that I just had to clean up with a toothpick. Overall the light is great! It's such a quick self-adhesive setting and you have such a choice of different light temperatures which are great for all skin types! You can find your best light and dim or brighten it. Only thing missing is a tote bag. I wish they recorded that. If you are looking for a portable flashlight that runs on batteries, this ring light is great as you have both battery and plug-in options. It comes with a plug. Batteries are not included but are easy to find on Amazon.
