Quintana Roo PR5 as a TT bike

Looking to get my first TT bike and considering Quintana Roo. I know they’re mostly used by triathletes but has anyone used it for flat course TT? Thoughts or feedback would be appreciated. Thanks

I forget the model but a mate of mine TT’d for years on a Quintanna Roo on all courses (hilly and flat etc) as long as you are not entering UCI events it’ll be fine.
