So because we tested it with wheelchair users, with wheelchair manufacturers, we got that feedback from them, not just articulating their problems, but articulating their solutions, and worked together to go back to the drawing board and make a new design, which we brought back to East Africa in '09 that worked a lot better than a normal wheelchair on rough terrain, but it still didn't work well indoors because it was too big, it was heavy, it was hard to move around, so again with that user feedback, we went back to the drawing board, came up with a better design, 20 pounds lighter, as narrow as a regular wheelchair, tested that in a field trial in Guatemala, and that advanced the product to the point where we have now that it's going into production.
Karena kami mengujinya bersama para pengguna dan pembuat kursi roda, kami mendapat umpan balik dari mereka, dan tidak hanya masalah yang ada, namun juga jalan keluarnya dan kami bekerja bersama untuk kembali membuat rancangan baru yang kami bawa ke Afrika Timur di tahun 2009. Dan alat ini bekerja jauh lebih baik di medan berat, tapi tidak di dalam ruangan karena terlalu besar, berat, dan sulit digerakkan. Dengan umpan balik ini, kami kembali merancang dan berhasil membuat kursi roda yang lebih ringan 10 kg, dan berukuran sama dengan kursi roda biasa yang kami uji di Guatemala dan kami membuat kemajuan sehingga kursi roda ini dapat kami produksi massal.
