Pro

• powerful light
• small (smaller than I expected - might be a negative for some)
• lots of settings
• bluetooth connection from cell phone works easily
• was able to get just the right blue-white-yellow balance

Contra

• doesn't come with its own controller
• the RGB stuff is just silly. I can't imagine what sort of weirdo would actually use them
• initial setting, before I set up my phone to change it: bright RED. Dude - this ain't Amsterdam!
