We couldn’t find any editorial reviews of this Hamilton Beach model, but at the time of our research it had a good rating on Amazon. Some reviews complain of a flimsy locking mechanism, but for occasional use we still think this model is a great buy. At around $20 (at the time of writing), it’s less than half the price of our top pick, and even cheaper than our other budget pick.
Manning-Bowman made an earlier version of the "Twin" called the "Twinover" that only had the thermometer. Because the "Twinover" is earlier, it may be a bit more valuable than the "Twin-O-Matic", but it lacks the convenience of the Thermostat. If you are an investor, go for the "Twinover" because it is older and rarer. If you want waffles, go for the "Twin-O-Matic." The trunion base is interchangeable between the two models, so it is possible that you might find a Twinover "iron" on a "Twin-O-Matic" trunion (or vice versa) This would most likely lower the value of the combined object. SO -- if you are buying one of these by mail or through an internet auction, please be sure to ask whether the trunion base matches the iron.

If you’re making a double batch, and want to keep your waffles warm, preheat the oven to 350ºF/ 180ºC and switch it off once it’s preheated. After that, make the waffles as per the directions and put them in the warm oven on a wire rack set on a rimmed baking sheet (avoid stacking them). I’ve also been known to put the cooked waffles straight onto the oven rack in the warm oven– whatever works best for you.
While this Cuisinart is undoubtedly a top performer at a great price point, it does only cook one waffle at a time, and the Wirecutter editors point out that it's not as sturdily built as some of the competition -- a point echoed by many users. That may make this waffle iron best for either small groups or occasional waffle-making. That said, Cuisinart offers a three-year warranty -- right up there with some pro-level appliances that cost six times as much. The Cuisinart WMR-CA is also versatile, with users saying it's even great for making foods like hash browns, bacon and potato cakes.
