I got my Oyama in yesterday ($44 shipped). Realized I had a bunch of unused Amazon points, so I blew them on this puppy:
https://www.amazon.com/Oyama-TRO-110C-Turbo-Convection-White/dp/B003XJE60U/
Surprisingly good build quality for the money. It consists of a base, glass bowl, and lid. The base has plastic handles & believe a ceramic bottom. The glass bowl is just a jumbo glass ramekin. The lid has the hairdryer piece attached to a glass cover. Pretty straightforward design...plug it in, set the temp (up to 482F), set the timer (up to 60 minutes), then push the handle with the childproof safety button down to turn it on. Not much to it! It is a very large unit. It includes a few accessories:
1. Short rack
2. Tall rack
3. Lid stand
4. Plate tong
When you first get it, clean it out (soap & water), then run it at 482F for 10 minutes to do an initial cleaning pass to burn off any chemicals from the factory. Reading through the Amazon reviews, there are some good tricks, such as lining the bottom (or the rack itself) with aluminum foil so you don't have to clean up the entire unit after cooking with it & also pre-heating the unit like you would a regular oven. I threw in a dozen wings this morning for breakfast (because who doesn't like honey mustard wings for breakfast? 80 grams of protein, baby!) at 360F (to compare to my Philips) & they came out okay...cooked yes, but not super crispy (whereas the Philips comes out crispy, but dry). Will try at a much higher temp next time to see if I can get the crispy aspect nailed down.
Size-wise, it's actually about the same size as the Philips, but the Philips is taller. Way more room in the Oyama. Higher temp, too (482F vs. 390F) & can go to any temp you want instead of 30-degree temperature jumps. I believe one of the reviews said that the Oyama takes about 10 minutes to pre-heat (will need to verify), whereas the Philips takes only 3. It's too early to really say for sure, but my initial impression is that this is a great buy at $44 & I wouldn't bother with a Philips AirFryer for 6x the price. Again, I need to cook a bunch more stuff with it to see how it handles, but reviewers are saying they can even cook stuff like bread in it without any issues, which is pretty awesome. I haven't used my Philips as much as I've wanted because if I'm doing something like sous vide, I've just restored to pan-searing it or breaking out my Searazall blowtorch to finish off small jobs. I will be baking a lot of cookies soon & will do some cross-comparison with my regular oven, my Breville convection toaster oven, and the Oyama to see how they each fare for baked goods.
First impression tho, great unit for $44. You definitely get your money's worth with this in terms of hardware!
