I bought the GoSun Sport Solar Oven https://www.gosun.co/products/gosun-sport and it arrived 3 days ago. I have cooked 2 meals in it so far. Pepper Beef, and Sausages and onions.
The cooking tray is a unique shape and I am looking for some simple recipes ideas for food that can fit in it. A little bit of liquid is ok, but I am unlikely to cook spaghetti sauce in it. It took about 1 1/2 hrs for the sausages and 2 1/2 hrs for the pepper beef which was cut into 1cm thick strips. The steak was incredibly soft, like sous vide steak. The onions came out soft and sauted, the sausages came out cooked and juicy with undamaged skins.
The general quality of the oven is exactly as it looks on the site. The glass vacuum oven is solid and strong, the flaps fold out and flexible but firm, the legs are a bit stiff to move, and we needed two people to confidently set this up without fear of dropping or breaking it, but it lives setup in the window we use for cooking with it now.
The cooking tray is easily cleaned after use, and there is an attachment brush that fits onto the end of the cooking tray to help clean out the inside of the glass oven tube. It holds enough food for two people.
I bought the preparation pack and am underwhelmed. The oven is great, but I can't get the torch to work and the power pack is yet to get enough charge to do a full refill of my device. The oven is too fiddly to turn to the boil water position all the time, but would be useful if I had a second on setup just for that purpose.
I get full sun for approx 6 hours a day through my kitchen window which made this a practical device for me. You need a sunny aspect if you want to use this at home and not just camping.
All round I am extremely happy with the oven, underwhelmed by the torch and charger and would like to buy a second oven to boil water or cook a second dish.
For the time it takes to cook things it doesn't sound worth it for the money. I can cook a sausage in a minutes with a bit of gas. I would hesitate to guess it will soon be put in the laundry never to be used again after a month of your use. Maybe good for camping or outing, but you can set up a small gas BBq in 10min and be eating within 15min. IMO
