I was unfamiliar with MobStub. I think it popped in an online ad. I logged on and was impressed with the prices. However, I had been "burned" by sites with weird names so I did my due diligence. They are an A+ with the BBB and it carries the Norton security icon with a current date. I decided to order three things for Christmas. One item were LED earrings. Not anything I would wear, but I thought it would be a wowzer gift for my 10-year-old granddaughter. I tried them out, and I was pretty impressed. They look really cool. One unfortunately was a little hinky with the light. You had to find the sweet spot before it would come on and then flickered sometimes. She probably could have worn it okay, but I decided to email MobStub about the problem. The next day I got an email stating they would replace the set... it was on its way. The other two items were fine and as described. I will order from MobStub again.
