I had a sensei (ambidextrous) which suited me fine but the twisted wire is worn due to friction, so I switched to a rival, only for right-handed (I'll be careful over this time !) the sensei was a lighter hair, this one with his 128grs, fine with me. Glide, soft full control, the handling is good (for large hands I have (20cm)) and lateral clicks fall well under the thumb of the click sounds are fairly discrete and the toothed wheel does no noise at all (I prefer) I do not regret my purchase in the frag sessions that rolls alone;) For 50 worth! Ordered Monday received the following Friday.
