I concur with above. Bought a pair of Ellipses when I 'got back into cycling' as back in the 80's all the good wheels had to have Mavic rims so it must be a safe bet right? Um, no!
Quit the opposite in fact. The quality was fucking BAD! The seamless laser cut join looked like it had been done with a hacksaw and soldering iron. Proprietary bearing system which was always either too loose or too tight. Customer service absolutely terrible. Never again.
Switched to Archetypes on Dura-Ace hubs and DT Swiss Carbon on DT Swiss hubs; all hand made; WORLDS apart.
Even if you want something cheap; the HALO wheels I had on my commuter were better made than the Mavics. Nowadays would recommend getting something with a wider profile.
