Received as a gift. I was surprised at the price of this unit when I came looking for the "I can't believe it's not included" tray. The controls are not simple enough to figure out just by looking at the icons on the control panel. I've never had to read a manual to operate a simple toaster oven. Just not user-friendly in my opinion.
Now the installation. As another customer mentioned, if you have an overhang of 1", then you're screwed (pun intended). Spacers are irrelevant if the screws wont reach the threaded holes. Almost zero chance of finding a screw to that's the correct length and has the same type of threads that will fit the holes. I looked.
You can throw the paper template away at this point. Since I wasn't going to wait a week for the chance I get the correct screws for my issue, I took matters into my own hands. Forget the holes. I just got four screws long enough to get through the metal rack. My overhang is 1" (all around). The plastic washer on top is probably 1/8". The rack is another 1/2" or 3/8". The shelf another 1/8" maybe. It comes with 2 1/2" screws (the long ones). For some reason, I couldn't find 2 3/4" screws so I had to get 3" length.
I first drilled four holes through the metal, positioned the mounting plate and duct-taped into place. Then with an awl (or anything pointy enough to fit), I made marks so I knew where to drill. On the rack itself, just make sure the metal "grippers" that come up through the metal plate are TIGHT so there's NO movement at all. I used a pair of pliers to bend them a little to tighten their grip. The oven attaches to these pieces and would normally be supported by the screws, if they were long enough, and the cabinet itself. Drill your holes following the marks you just made. For the less experienced, you need to be mindful of the size of the hole you drill so that it's just large enough for your new screws to fit easily though.
In my case, the rack fit just inside the "overhang" so I had to use the spacers. For me it was two large and two small. Drop the screws down through the supplied plastic washers. I used a simple piece of tape to hold the washers up under the cabinet to allow getting the screws through the holes I drilled through the metal plate. Good to have some tape already to go so you can hold the mounting plate in place while you get the other screws through their holes. Now I added large metal washers then the nuts I bought that fit the new screws. Boom. Tight as a drum.
On other complication for me was my 3" screws. They're too long and won't let the oven fit into it's brackets. You could use a hacksaw, but it's difficult in that tight space. I happen to have a Dremel rotary tool. I was able to cut the extra length off pretty quickly, but I did show myself with a LOT of sparks. It was New Years Days so I didn't mind.
I think the only problem people are having with getting the oven to mount at this point, is you have to put the back end in first, the use a bit of force to pull the oven by its front legs so you can get it to "hook" into place at the front. I didn't get it the first time, and I'm good with handyman stuff. Once I pulled a little harder, it went right into place.
Did I mention there is NO tray with this unit? That blows my mind. The name of the product has the word OVEN in it, not just toaster.
Spouse 1, "Hey honey, let's make some quick french fries or cookies in our new toaster oven, it's easy..... oops. Sorry. We can't. It didn't come with a tray."
Souse 2, "That's weird."
