Magnifying Glass In Headgear for close inspection!

I was up late watching jewlery television and they advertised a nice 200 gram digital scale for only 29 bucks!
and then the advertised this cool tool for examining your buds!

only 9.99!
this is a very good deal!

looks like a nice peice of kit but there wasent any specs telling what magnifacation it was
so it probally will be a shit magnifation at that price
cheers all :)
