These are great little devices and are 100 times easier to use than trying to connect bulbs with wire.

electricity review
 
I purchased the bulb holders along with bulbs, batteries, and wire so my kids could make complete circuits. They had a great time. These products arrived with no damage and all wroked perfectly. I plan on purchasing again next year.
