Lmao...99 CAD is the MSRP for these? Geezuz... Ultra is TMart's TLife V8 Pro rebranded and updated slightly (battery life mainly from the looks of it). 18 bucks is about all they're worth, and that's pushing it. The magnetic on/off feature is an absolute nightmare and the build quality is questionable. Everything else is decent though.
