Used K.U.M. Rage while cleaning some stainless steel accessories and it performed consistently over multiple uses.

Really happy with K.U.M. Rage 28ml overall. Fresh bottle, good consistency and much more confidence-inspiring than some bigger brands lately.

K.U.M. Rage arrived properly filled and professionally wrapped which already put it ahead of a few competitors I’ve tried recently.

K.U.M. Rage 28ml ended up being much better quality than expected. Bottle arrived looking fresh with a proper tight seal.

Used this while maintaining some urethral stainless steel gear and the product quality felt reliable from the start.
