There is a definite difference in quality/feel between the NRG and WB. If you don't know already, NRG is a replica of WB. So of course it's gonna "look" and "feel" cheap. To be honest, though, the NRG does what it does and is a good purchase for people who don't have or want to empty out their wallets. I would recommend you to just keep the NRG since you've already got it.
