The Sharp R890EST is a 32 L Australian-market convection microwave with microwave, grill and fan-forced convection modes. Its listed specifications make it more versatile than a microwave-only unit, but available documentation does not establish how well it cooks in practice. The model is also labelled discontinued by one review platform, and published dimensions conflict—two reasons to verify fit and availability before considering one.
What does the Sharp R890EST offer?
Sharp Electronics Australia describes the R890EST as a stainless-steel inverter convection microwave. It combines everyday microwave functions with grill and convection cooking, plus automatic programs and sequence cooking. Those are feature claims, not evidence of independently tested cooking results.
| Specification | Sharp-listed detail |
|---|---|
| Capacity | 32 L |
| Microwave output | 1100 W |
| Convection power | 2100 W |
| Grill power | 1100 W |
| Power levels | 11 |
| Automatic menus | 28, covering reheat, cooking, defrost, melt/soften and baking |
| Turntable | 315 mm |
| Other listed features | Favourite key, child lock and four-stage sequence cooking |
Sharp’s product documentation says Smart Convection/Combi alternates microwave power and fan-forced convection heat. The stated aim is faster cooking with a crisp, browned finish; that is the manufacturer’s description, not a verified performance result. See the R890E specification sheet and Sharp’s R890EST product page.
How good is it at cooking?
The published specifications describe what the appliance can do, but they do not establish cooking quality, speed, temperature consistency or ease of use in real kitchens. No independent cooking test is established by the available sources, so it would be misleading to call the R890EST a proven performer—or to infer a result from its wattage and mode list alone.
#1 Best Overall
- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
For a buyer, the practical distinction is clear: the R890EST offers more cooking modes on paper than a microwave-only model, but whether that versatility matters depends on how often you would use grill and convection functions. If you need a dependable oven replacement or have a specific baking requirement, seek hands-on evidence for that use rather than treating the feature list as a guarantee.
Will it fit your kitchen?
Published exterior measurements do not match. Sharp lists 520 × 312 × 477 mm, while Appliances Online lists 520 × 315 × 510 mm. The sources do not explain the discrepancy, so do not choose a cabinet or countertop location based on a merged or assumed measurement.

The R890EST is freestanding by default. A cupboard installation using a trim kit requires both the compatible EBR39ST trim kit and the EBR89ST vent kit. Sharp confirms EBR39ST compatibility and says the microwave is not included with the trim kit. Sharp’s EBR89ST listing says the vent kit is mandatory for R890E-series convection microwaves when used with a trim kit.

What do owner ratings and availability tell you?
ProductReview.com.au labels the model discontinued and showed a 2.1 rating across 17 reviews in a page snapshot accessed on 7 October 2026. That figure is a changeable platform snapshot from a small, self-selected set of reviews, not a reliability study or a representative failure rate. Owner anecdotes can help identify experiences to investigate, but they cannot show how commonly a problem occurs.

An Appliances Online product page exists, but a listing does not prove current stock. Current availability and price have not been established. If you are considering used stock, check that the unit is complete, inspect its condition, and confirm that its manual and installation requirements suit your kitchen.
Verdict: who should consider the R890EST?
The R890EST may suit someone seeking a 32 L microwave that also provides grill and convection modes, provided the buyer can verify the appliance’s condition, fit and availability. Its feature set is documented; real-world cooking performance is not independently established here. The conflicting dimensions and possible need for two installation kits make checking the manual and installation plan especially important before purchase.
