Given the tremendous functionality, and especially for the price, I cannot in good conscience give this oven less than 5 full stars.However, that is definitely not to imply that it is perfect.Nothing is, and this is no exception.So, while others here have done a fine job of highlighting the positive aspects (which is in fact why I bought one, too), I will try to provide a more balanced perspective. First, though, a quick re-cap of those highlights.Yes, this oven really does do the job of three: a conventional microwave, a convection unit, and a toaster oven.In fact, that does not do it justice because it does even more than that.You cannot, for example, grill a burger in any of those types, but you can in this.Especially for a small kitchen, this is phenomenally useful.In just a couple of weeks, I've already become reliant on its non-microwave functions for a variety of things, from roast chicken to frozen French fries, both of which come out better than in my conventional oven and in much less than half the time.And cleanup has not been an issue.
Still, there are flaws.Others have noted the wobbly turntable and difficult to read LCD display, and this is true - but I think there are more serious ones.I'll start with build quality since that was the first one I encountered.I've unfortunately had a chance to explore this in-depth, thanks to a broken fan assembly in mine.This was not shipping damage, either, but a manufacturing defect.In checking out the problem, I was able to examine things on the inside, it was clear that the unit is built to a very tight price point.There is an abundance of crimped sheet metal, a minimum number of screws, and cheap plastic snap-ins securing (barely) too many of the vital components.I'll also note that Consumer Reports has been reporting failure rates for Sharp built-in microwaves (the only variety they track reliability in) many times that of the other brands.That said, this unit replaced a Sharp countertop microwave which was still going strong at 13 years.Another weak point - this time of the design - is the ratio of exterior to interior space.In other words, the cavity is quite small for the amount of space the oven takes up, even compared to other convection units.In fact, my counter can just barely accommodate its depth.This is likely partially the result of its `economical' design.Also related to that, no doubt, is the omission of a doneness sensor, which I would expect on any microwave at this price, convection or not.This sensor is what allows a microwave to automatically reheat dishes, and shut off when it detects, through the amount of steam given off, that a dish is done heating.Instead, we are given reheat presets, which are never adequate (unless maybe you weigh your food first and configure it just right on the plate).
However, not all the preset programs are useless.In fact, much to my surprise, some are invaluable.I expected that all the co-called `Compu-` settings were simple time presets, but this is not the case.Many of these are fairly complex cooking routines, sometimes involving all three methods in various sequences.For example, the Compu-Roast 1 program will cook a darn good roast chicken automatically, using microwave, convection, and even the upper grill for browning near the end.The hamburger Compu-Grill program works similarly well, though I believe with just the 2 grills.(It is not always possible to tell what cooking mode is being used).These programs make it simple for even a mediocre cook like myself to begin using the oven instantly and with good results.And it prevents it from becoming merely an overpriced microwave (like my mother's KitchenAid has: it has convection and an upper grill, too, but no programs, so they remain unused after 2 years).Nonetheless, the presence of such helpful programs does not preclude it having a doneness sensor which is virtually a standard feature these days.Ideally, it would also have a linear power supply like the Panasonics do, allowing truly low-power microwaving, rather than simply cycling full power on and off to simulate low power operation.But not many other manufacturers do this, and that may be expecting too much.Finally, beware that this oven will draw more current than a comparably-sized microwave-only unit: up to 13 amps.This can tax a typical 15 amp household circuit if anything else is plugged in.Add a toaster, for example, and you will trip a breaker (I have).
To summarize, while the build quality is a concern, very few ovens I am aware of offer as much functionality to bake, roast, microwave and grill - and fewer still offer preset programs making all that flexibility readily accessible.None do it for so low a price.In fact, of the few other countertop convection microwaves I could find, nearly all were over three hundred dollars actual selling price.That makes this unique oven a bargain in several ways.

We had the lower model of R-1520 and we really liked it. Because of an accident we had to replace it (I didn't do it. I wasn't even home). We have a certain look in our kitchen and we like a microwave that has the control panel hidden. (Most controls look cheap and flimsy.) Although this model is not the highest rated out there it still does everything we need it to do. All I can see that it's missing is a center rack so you can place two items inside at once. I installed it by myself and found the instructions to be easy to understand and the installation simple. It is a bit heavy so you may need some help lifting it. My doctor says I should regain full use of my legs when my back is out of traction. (Just kidding.) If you are looking for a good-looking, well built, easy to operate, nice featured, easy to install microwave I say this is a good choice.
