White And Reflexive Mylar

I've brought white mylar, kinda by accident http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=280633603001&ssPageName=STRK:MEWNX:IT#ht_2436wt_905

Is it any good?

Is it worth sending it back and ordering reflexive? I'm only doing my first 1/2 plant grow so i think it would do, but i'm not pro.

Thanks for the help

That is great!! Use it.

that stuff is the best i think and its all i use that other stuff makes heat spots and is no good stick with the black and white one

Thats good then , thought i had brought the wrong stuff!
