updating my review because after using these at our event again, I must say that although the lights are thin and break easily, it does keep the strings light for hanging and in our case the weight must be light in order to not pull over our decorations.  For this reason, I purchased two more this year! 

I've bought these several times but only so they matched the others.  Unfortunately, I will need to replace them all.  The problem with these are the bulbs.  They are so thin, they break at the slightest touch (against each other, when screwing them in, etc.).  Additionally, they come with the bulbs separated and must be screwed in (takes some time when you buy 4 strings +).  I'd rather spend a few bucks more to get something more durable and already put together.
