I love the simplicity and convenience of the design. It’s so easy to quickly switch grips - straight, overhand partially pronated, underhand partially supinated.
The annoying flaw? Three of the four rubber pads fell off on the first use. This is a problem that Kensui is aware of - as numerous reviewers have pointed this out - and should have been corrected by now. The manufacturer attached the pads with rubber cement (a terrible choice of adhesive for this application). Kensui recommended super glue to reattached the pads. This would likely work better than rubber cement, but the more durable fix would be a 2-part epoxy. I decided not to reuse the rubber pads - I picked up some felt furniture pads (with adhesive backing) from Lowe’s and cut them to shape. Works better than the rubber pads, anyway.
You should expect to reattach or replace the rubber pads (sooner than later). Otherwise, it’s a good product.
