Guys is this better than using stepdown transformer http://www.ipmart.com.my/main/product/EU,P...php?prod=414404

the 3 pin plug is confirm a imitation product, it even save the cost and no xb1 logo on it, please do not buy this as your new machine deserve better!
also i would not advice u to use the cheap stepdown, in case anything happen u dont want to risk your new xb1

so u only have two choice unless of cos u buy a uk set:
1) buy a better transformer which cost around 150-250
2) mod your ori adapter, u can send to kelvin to do it and i think alot of us did that, and is working great!

just sharing my thought la, cos i didnt want a big transformer in my living room. and since many people mod their adapter and have no issue i thought i just take the chance! is really up to u la......
