Buztronics 4 Pack Color Change 1-1/4-Ounce Light Up Shot Glasses

One of the four shot glasses I received was defective. It did not work at all, and after tampering around on the inside a bit I was able to make it flash red for a few taps. Also, confusing product description- claims that batteries can not be replaced followed by comment on replaceable battery. To be fair- the product did arrive 1-2 days after ordering. Overall, it should be cheaper, as tape was involved in the creation of this product.

These light up when you pour a liquid into them, but the lights quit after about 15 seconds. The plastic in a little on the cheap side and the batteries are not replaceable, however they are somewhat of a conversation item and serve the purpose. You can tap the bottom of the shot glass and they will recycle through another 15 second light episode.

I was very disappointed in this product. I thought it was already colored rainbow, and it actually is battery operated and the base is black, looks big. When not lit up the shot glass is a frosty shade. I hated this product and returned it.

These are very well made! The light source is completely separate from the liquid, so there is no danger of shorting out the light.

I bought the shot glasses for a Christmas gift to go with some liquor I wanted to give a young man that requested that kind of gift for Christmas.
