Nah, I wouldn't say I was disappointed with them per say. I just prefer the clear lens LED's as you can generally tell when they are or aren't on in broad daylight. I hadn't powered these up yet, but after having done that, they do put out a good amount of light for desktop use.
Here's a picture of my 10 yr old son wearing it, he soldered it together himself. I bought the kit for him to solder, as I've been looking for something novel like this for him to get more soldering experience on.
Thanks for the great kit.
