I bought the Global Sun Oven even though I ‘m quite happy with my do it yourself solar oven. The commercial Sun Oven is going to last longer and the materials used no doubt meets safety standards. I noted it is an unfair comparison because I have not peeled the blue plastic film off the reflectors of the Sun. Surprisingly, both ovens are just a few degrees apart for now.
I will continue to tweak my own diy oven. More videos will come when I start using the Sun Oven.
