Ronbus Refoam R4 14mm Pickleball Paddle Review

MATT'S VERDICT

The Refoam R4 is the hybrid shape in the Refoam line, with a wider face and a noticeably more usable sweet spot than the R1 elongated. Same MPP foam construction (plush, dense, no hollow echo) and the same 3D carbon lattice keeping off-center hits stable.
