They worked very well. They are easy to use and respond well to music etc. The only thing I didn't like was that there is no button for the Blue with stars light combo. That was the combo I was hoping to usefor a gender reveal, so I ended up putting one on blue & the other in stars, but if you are just using one light, it isn't possible. The light DOES that setting(u can see it in the flash mode etc) but there just isn't a button for it. Personally I think it's the prettiest setting, and it would be nice to be able to have a button to use it. I'd give up the red/star or green/star combos for it.
