Before we decided to spend so much money on the product, we did some research. We were able to find excellent reviews and the price is reasonable. You can personalize the messages and choose from any of the presets created by others. Your device's app will link quickly to the glasses to allow you to control it. It's very user-friendly. After taking them out of their boxes and admiring how amazing they are, you can connect them to your phone and start using them. These are great gifts and I will be buying more. These glasses are great for large events such as parades, raves and cookouts. These glasses will be a hit with anyone who likes attention.
