Can the Binovue be used without its 2x Barlow ?

I'm a newbie who's take the plunge and ordered a TV np 101 with Binovue. Now I'm considering the purchase of some pairs of new eyepieces for the Binovue. After reading many Binovue posts here and on other forums I'm still not sure if the Binovue can be used with its 2x barlow removed, allowing the eyepieces to be used at their normal magnification. One vendor I spoke with receommended against trying to use the Binovue with the Barlow removed, but I couldn't tell whether it can't be done, or just that it's a cludgy workaround of some sort. Anyone out there had sucsess with this ? thanks all
