english: 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.
non_english: Pošto smo ga testirali sa korisnicima invalidskih kolica, kao i sa proizvođačima, od njih smo dobili povratne informacije, koje opisuju ne samo njihove probleme, već i njihova rešenja. Zajedno smo se vratili na projektovanje i smislili novi dizajn, sa kojim smo se vratili u istočnu Afriku 2009. Ovaj dizajn je funkcionisao bolje od normalnih invalidskih kolica na teškom terenu, ali još uvek nije dobro funkcionisao unutra jer je bio prevelik. Bio je težak i nepokretljiv, tako da smo se ponovo vratili na projektovanje sa tim povratnim informacijama. Smislili smo novi dizajn proizvoda, lakši za 9 kilograma, uzak kao normalna invalidska kolica i testirali ga na terenu u Gvatemali. To je toliko unapredilo proizvod da se on sada i izrađuje.
