Great Product and Great Customer Service
Color: Stainless Steel
This little countertop oven checks all of the boxes for me.
First, even at its highest tempeture for baking bread at 450 the outside of the unit is warm to the touch but will not burn your hand.
It has all of the settings one would want for an oven to do icluding, reheat, PROOF (for bread) broil, stay warm etc. I love it and the best of all of this was my experience with their customer service. I started having an electrical glich with the unit soon after I bought it and reported the problem to the company. Well, then it stopped having that problem but intermittently did. The light would come on by itself and sometimes I could not get the oven to turn on. So, this ensued off and on for several months until I decided to once again contact customer service to report my problem. They took my information and then informed me that they would be happy to replace the unit. All I needed to do was send my unit back after receiving the replacement. Which they did and I did and VOILA, problem solved just like that. No rigamarole, no hassle just excellent customer service.

Fantasticallly engineered oven, cooks quickly and evenly, may need to adjust recipes
Color: Stainless Steel
4.5/5
This Typhur Sync Oven is a thoughtfully engineered toaster oven air fryer that has some of the best air fryer capabilities you can get out of a toaster oven air fryer, on par with and potentially more even cooking than the often superior basket air fryers. This is largely thanks to its fan placement and size, which is very similar to basket air fryers: large (roughly 6-7") and positioned over the top.
This large fan moves a lot of heat quickly and evenly, leading to really even cooking and much shorter bake time.
This oven looks and feels well built, with the walls being relatively well insulated stainless steel sheets (not a ton of heat emitted from it), heavy duty hinges, and primarily stainless steel accessories (and an enamel coated roasting rack).
There are multiple fan settings depending on the preset chosen, though the fan unfortunately can not turn off except for the proofing feature which has a low max temperature.
The temperature probe that comes with it is really easy to use and store. Racks can still be stored on top of the toaster oven without much issue even though the probe is also stored on top. If you're not careful you might tap the probe or knock it off, but unlikely.
Cooking is very even and quick. The Typhur cooks quicker than my previous toaster oven, and much more evenly. You may not need to move food around when air frying it, which is really impressive. Cooking is so quick that things may burn if you cook them at normal times. You may need to reduce cooking time by more than 25-30%, or lower temperature so things can cook more evenly inside and out, given fast convection cooking more noticeably cooks the outside more than the inside.
Couple cons:
- The only real issue I've noticed is rarely when heating up something in the top of the fan will vibrate slightly, which is mildly annoying and can shake the pans on top of it. Tapping the top of the oven will usually stop the vibration, which makes me think there may be a bit of play near the fan/heater. This issue rarely occurs.
- The cookies setting runs the fan on low speed, but it's still moving enough air to keep heating even. The problem is that because the oven is so much faster at cooking - even true on the low fan speed cookies preset - that larger cookies may be undercooked on the inside and/or darker brown than preferable on the outside. If I want my batch of large cookies to be cooked perfectly, I still use the conventional oven. This convection oven works quite well for smaller cookies though, and well enough for larger cookies if you figure out the right temp. The toaster oven recommends 330F for cookies, often 325F is recommended (25F lower than normal 350F), but I've found that even 320F is too high of a cooking temp for larger cookies, as they can be fully cooked on the outside but raw on the inside, like was the case with my 100gram (~1/3rd cup) chocolate chip cookies cooked at 320F. My 80g sugar cookies cooked at 300F seemed more similar to conventional, but were still more browned on the exterior than desirable.

Best Christmas Present this year!
Color: Piano Black
If you love that soft, crunchy “nugget” or “sonic” ice, this ice nugget maker is an absolute game-changer. It produces perfect, chewable ice with a satisfying texture that elevates everything from water and soda to cocktails and iced coffee. The machine heats up quickly, churns out ice fast, and keeps a steady supply going without a lot of babysitting. Setup is simple, and the compact design fits nicely on a countertop without feeling bulky.
What really stands out is the consistency and quality of the ice—it’s light, airy, and never rock-hard. The machine is also surprisingly quiet compared to traditional ice makers, and cleaning is straightforward, which makes it easy to use daily. While it’s an investment compared to basic ice trays, the convenience and restaurant-quality ice make it 100% worth it. If you’re an ice lover or entertain often, this is one of those appliances you’ll wonder how you lived without. Just as good quality as the expensive machines.

Excellent Ice Maker
Color: Piano Black, Color: Piano Black
This 100% beats the heck out of the Frigidaire Gallery countertop nugget ice maker I had. The ice making is faster, the nugget quality is better, cleaning is easier AND it is waaaaay quieter than the other one. Let's start with the speed of the ice making. Within 15 minutes I have ice. Enough for at least a cup. The nugget: soft, easily crunchable, perfect sized just like that Sonic ice! Noise is basically non-existent compared to my previous machine. I don't even know this one is running most of the time unless I look over and see the display. Cleaning: It comes with packets for cleaning. Pour one in, set it to clean and in about 7 minutes it is done. I run mine with the same packet twice then drain via the easy to access drain plug in the bottom of the water well. Then I rinse twice and start it making ice again. I have an alarm set.for a reminder to clean it monthly, but I dont really need it because I can tell by the way the water looks in the well that it needs cleaning. Also, I always make sure to wipe down the sides of the well and wash the ice basket once monthly. I wish I hadn't wasted my money on the Frigidaire. Their warranty is a joke because it is no longer made by actual Frigidaire. I just tossed in in the trash. I didnt even get 3 months out of it before it started screaming and dying.

It runs a short period of time then stops with error codes.
Color: Piano Black
My husband had openings heart surgery his hospital stay was 9 days. During those 9 days, his only joy was the ice that the hospital had. So he asked me to order a machine that made that small crushed balls of ice. So I ordered this one.
It arrived nicely packaged.
It made wonderful ice. I only used water that was filtered with very good filters. Shortly after running it, I got an E1 error code. So I reported to the manual. There was no code listing for exact issues. So I chose to clean it ( whi h I thought was premature but had to try something). I followed the instructions on cleaning. It started to work again. Worked for another short wile then got the same code. I cleaned it 3x to find the same error code.
So I returned it and was awarded a full refund.
