To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
Served their purpose as an addition to a "mad scientist" costume. I only gave it 4 stars because they were not able to withstand the g-force sustained from 1.21 gigawatts. Unable to see through the lens which was a gift and a curse. A curse because I was unable to use them properly while conducting my model experiment, but a gift because they blocked out all the haters (I'm looking at you Biff)
Very poorly and cheaply made. The band that connects the two eye pieces is held together by a small bump in the rubber band. That's it. Also, the glasses are not clear. They are purposely foggy and can not be worn over your eyes at all, not even as a costume or prop piece. You can only wear it on your head or around your neck. It has no practical use.
Wore these along with my Ghost Buster costume, I was Holtmann, and it was epic. Nice glasses but fragile. Make sure to peel off the thin plastic paper on the front AND back of lense or you wont be able to see through them.
