The Sharp R930CS 1.5-cubic foot Countertop Convection Microwave in Stainless Steel and the Sharp R1875T 1.1-cubic foot 850-Watt Over the Range Convection Microwave Oven in Black are generally given high ratings by consumers on HomeDepot.com, with both receiving over four out of five stars as of 2016. The Sharp R930CS receives a slightly lower rating on Amazon.com, where consumers give it 3.7 out of five stars.
The Sharp R930CS features a capacity of 1.5 cubic feet, 900-watt cooking power, a four-way convection system for baking and an internal smart sensor. Satisfied buyers on HomeDepot.com state that it bakes dishes well and at reduced cooking times, that it effectively combines the functions of an oven and microwave into one appliance, and that it’s easy to install, use and clean. Less favorable reviews say that the appliance does not have a long lifespan and it is poor quality. Consumers reviewing the same model on Amazon.com positively note that it has useful settings, the smart sensor works well and the instructions are easy to follow. Customers who have mixed feelings say that it’s a great oven but a poor microwave, and that the cook time is fast, but the poor-quality turntable motor barely handles the food weight limit.
The Sharp R1875T offers a capacity of 1.1 cubic feet, 850-watt cooking power, 25 automatic settings and a built-in exhaust system for installation over a cooktop. Customers who highly rate the product note that both the convection and microwave features work well, and many specify that this was a second purchase of a Sharp microwave following positive experiences with the brand.
