I actually used this to propose to my fiancé (she said yes). :)
I'm glad I did it, but the build quality of the product is lackluster. The first one they sent didn't work and then they sent me another one that spontaneously stopped working. Fortunately, I was able to flash the software on one of them to get it working before the proposal, but I wasn't confident that it was actually going to work.
Their customer service is very good though. They were very helpful and sent me a personal cell phone number to troubleshoot.
