I bought the InstaBulbs on-line in November of 2012. It worked great for about 1 week.
I thought it was the batteries, so I bought the expensive brand that suppose to last LONGER. I replaced the batteries and, again, it worked great for about a week. So, then, I tried the other INSTABULBS, and, you guessed it, the same outcome. I rarely use it.
Just to find things in the morning, so I don't wake up my husband or such the same.
I can't return it, it is passed the 30 Day refund trial. That's what I get for impulse buying.
Monetary Loss: $38.
