ZERO Z5s

The Evnroll ZERO Z5s stands as a single release within the ZERO line, a full size mallet built around what the maker's page describes as a reverse offset hosel designed to aim at the club head's center of mass, aiming for zero torque through impact. Evnroll's own product page frames this as the foundation of the design, tying the shaft position and hosel geometry directly to face stability rather than treating them as separate features.

Australian Golf Digest, reporting on the release, described it as a modern mallet of milled construction, noting a design feature where an opening in the middle of the head is formed by a back bar joining parallel heel and toe arms. The same outlet reported the Z5s was available for pre-sale October 1 and at retail October 31. Pluggedingolf.com, in its own reporting, tied the model's zero torque design to a nod toward Guerrin Rife, calling him a well respected putter designer, a framing that sits alongside but distinct from Evnroll's own account of the hosel's origins.

On performance, pluggedingolf.com's reviewer called the Z5s a favorite among the three ZERO models tested, praising the ball's repeatable turnover and good distance control even on off-center strikes. That view stands as one reviewer's account of a single release rather than a verified measurement, and with only one entry on record in this line, the Z5s currently represents the whole of the ZERO story as this house holds it.
