Bought this as a replacement for our old Sharp Carousel. It’s much like the old one with a few more features. I gave it only 4 stars for a couple of reasons, it wants to slide on the counter top when you open and close it (I put a piece of wood between it and the wall to fix) and, I think the control panel could be laid out better (why aren’t the “Start” and “Stop” pads highlighted and seperated out from the others). Over all, this is a very nice microwave and I would make the same choice again.
P.S. My wife has no trouble with the control panel, so maybe it’s me.

I bought this for a substitute oven while my kitchen was being redone and all my facilities were not connected. It got me through the month great and I ended up selling it to my painter when I was done with it

The first Microwave I got was damaged in shipping. I called Sharp and they had someone come out and look at it. We were told to send it back and Amazon sent me another one right away. The service was excellent and I wouldn’t hesitate to buy anything else from Amazon! The only thing I don’t like is that it makes a loud noise when opening it and closing it, which makes my daschund bark every time. Otherwise, I love it and use it every day.

Some appliances, while highly touted in the ads, don’t hold up well under day-to-day usage. Not so for this microwave; the Sharp R-420LK is a great performer! Sharp R-420LK Family Size Countertop Microwave Frankly, I’m not your average once-in-awhile user; I cook full meals in my microwave and put it to the test daily. It’s quiet, efficient, thorough, and a great workhorse. My family of boys puts it through its paces almost effortlessly. The sensor feature allows for one-button defrosting, reheating, and cooking. Any of these functions can be done manually as well. And to date, it hasn’t burned a single bag of popcorn. Matter of fact, it pops every kernel to perfection!

In addition, the Sharp R-420LK is roomy and attractive, easily matching my kitchen decor. While this model was rated highly by a leading consumer magazine, it was not carried by local retail stores (and I live in a major metropolitan area). So to Amazon I turned and they did not disappoint! Ordering was easy, the microwave arrived promptly and without a scratch, and set-up was a breeze.

So much for the high points. What about the low points? Very few, and easily adjusted for. Simply, the cooking sensor isn’t perfect; with the first use it didn’t cook a full pan of chicken parts thoroughly. So, I’ll simply use the manual controls when I cook full casseroles and meats. However, the appliance does reheat and defrost meats, breads, and leftovers quite well via the sensor. Also, I would like to change the “Minute Plus” button to a “cook by 30 second increments” button as on our previous microwave. Then again, that was one of the few redeeming qualities of our previous microwave (GE), one that would burn popcorn easily, trip our home circuit breaker with power surges, and actually rusted out after a few years of use. I’ll take the Sharp R-420LK anytime!

The 16 year old, second hand Sharp microwave gasped its last breath much to our dismay last weekend. Distraught with the idea of “real cooking” I immediately turned to the mircowave reviews on Amazon. Thanks to all who proceeded me in their reviews, you did not lead me astray. The mircowave arrived within 2 days with a hail of trumpets. As previously stated it has more bells and whistles(love the sensor cooking feature) than my old model, is large enough to cook for a family, has plenty of power to kick around, the turntable can handle anything and is working away in our kitchen (Thank the heavens!). I have no doubt is will be as reliable as its predecessor. The really great part of this is that I didn’t even have to leave the house and could compare brands and models from actual users. People who review on Amazon all deserve a badge for helping other consumers choose wisely.

Thanks to all who review!

After 12 years of hard use my last Sharp Microwave finally went belly up. I researched all microwaves and came back to my original thoughts….buy another Sharp!!!
Purchased the Sharp R-420LK Countertop Microwave through Amazon and it is amazing. Sleek and ergonomic with preset programs to do almost anything. Cooks flawlessly and looks great to boot. I highly recommend this excellent product to anyone looking for a countertop microwave.

cant beat the price and free shiping- this is really a nice microwave. All kinds of settings-sensor cooking feature is super-turn table is great.
I am glad i ordered it.

I bought this item to replace a similar model I bought ten years ago from Sharp. I was so happy with the old model and it still worked, so I gave it to my brother. I wanted to update my kitchen and could not find this model in stores so I went to the internet. The only complaint I have is that Sharps descriptions of the R-410LK and the R-420LK left me a little confused and I ordered the R-410LK by mistake and had to send it back. The R-210LK works by computing the time you need to cook something rather than by sensor, the R-420lk cooks by sensor. Those sensors make it so easy. Now that I had it over a month, I can tell you I love my new microwave as much as my old one.

My 15+ year old Samsung microwave finally died (to my wife’s rejoicing…) and I had to find a new microwave to fit on the built-in microwave shelf of our kitchen. The R-420LK won the battle based on the dimensions available and the features (I wanted sensor cook and lots of power).

The first unit that I received from Amazon had some sort of super-adhesive on the ad glued to the front of the door. When I went to remove it, the glue smeared all of the shiny black door. Nooooooo! My wife was not happy, so I contacted Amazon and they agreed to replace the cosmetically blemished unit. I received the replacement (which had normal adhesive on the front ad) and configured the unit. (Great job by Amazon!)

Wow, does this thing cook! It has to be twice as fast as the older microwave that it replaced. I have to use about 2/3’s the time listed on the packages for frozen food, or it will burn things. I’m still getting used to the cooking times, but am quite impressed with the performance.

We like that we can fit the 8×11 baking dish inside, and the fact that it makes perfect popcorn automagically.

All in all, I’m happy and hope that we get several years of life out of this thing, as that would be the only downfall that I could see.

This is my 3rd Sharp Carousel microwave oven. The first one was a combination microwave/convection oven. After about 10 years, the knobs broke and I used that as an excuse to buy a replacement (the original still works). The replacement I bought next was a digital model in most respects similar to this one. Again, it lasted about 10 years before developing some rust spots along the chamber seams. Again, although it still works, I saw this as a potential fire hazard and replaced it with one as similar as I could. buy.

At 1.4 cu.ft., it’s big enough for just about any use we (family of 6) have for it. With 1100 watts on tap, it cooks very quickly so I usually have to adjust cooking times down from what’s recommended. No matter, though, Sharp’s Sensor Reheat works extremely well on leftovers or just heating canned goods. It does all the usual things, like popping popcorn, effortlessly.

The only thing that’s changed significantly since I bought my last one a decade ago is that the price has gone down! I really love this microwave and wouldn’t consider buying anything other than a Sharp Carousel in the future.
