My son and I have been using Otter Mesh since it came on the market-- about two years now. I have tried out all the mesh offerings-- ECM, Throne, Gonzo, Jimalax, StringKing 1 and 2s... Put quite simply, this is by far the most outstanding mesh I have used. The strength, consistency, and lightweight are unparalleled. And while the $40 price seemed quite steep when it came out, the new mesh offerings (Hero Mesh, StringKing 2s) are all moving upwards in price to around $30. You get what you pay for with Otter Mesh. My recommendation is to use StringKing sidewalls and shooters with Otter Mesh. Placed into a Rabil 2X, it''s flat out amazing. I just ordered another piece of Otter Mesh to replace my worn out piece. Yes, Otter Mesh does wear out, like all mesh pieces. Expect Otter Mesh to last no more than a year of near daily use. But that''s about the max you can expect with any mesh (accept hard mesh, which doesn''t get good until about.a year old).
