Sharp R395EST 34L Inverter

The R395EST is the Sharp inverter microwave that has quietly sat in the $329-379 bracket at Harvey Norman and The Good Guys for years. It has the biggest capacity in this review (34L, which matters if you roast a chook in the microwave, which you should not do but some people do), the highest wattage (1200W), and proper inverter technology. On paper, it should be the best value in the group. In practice, Sharp Australia cut the warranty in half in 2023, and the long-tail reliability data is mixed.

Correction before we go further: this unit is 34L, not 33L, and it is an inverter microwave, not convection. The Sharp Australia product sheet confirms both. Earlier versions of this review (and several retailer listings) had the specs wrong. The R395 model code has gone through multiple iterations over the years with the same slug but different internal hardware, which probably accounts for the confusion.

What it is like to actually use

The thing you notice first is raw power. 1200W is 100W more than the Panasonic and 200W more than the Samsung. A mug of coffee reheats in 55 seconds instead of 70. A plate of leftovers is hot in 90 seconds instead of 2 minutes. This sounds trivial until you live with it, at which point it becomes the reason you prefer this microwave to your partner's.

The flatbed-style turntable is the other genuinely useful feature. Square casserole dishes, rectangular trays, anything that does not play nicely with a standard round turntable, all rotate smoothly. The turntable is still there; it is just bigger and sits flatter, giving more usable floor space.

The control panel is Sharp's usual: a dial on the left for power, a keypad for time, preset buttons along the bottom for popcorn, beverage, reheat and weight defrost. No touchscreen. The keypad is tactile rubber and wears noticeably after a couple of years (the 3, 5 and 0 buttons go glossy before the others).

Torture tests

Defrost 500g of mince evenly without cooking the edges. Inverter defrost at 500g setting, 7.5 minutes. Similar result to the Panasonic. Edges are soft, centre is soft, no grey cooked rim. The 1200W power means it runs slightly hotter during the cycle but the inverter compensates well.

Reheat leftover pasta without a dried-out ring. Covered bowl, sensor reheat, 2:10. Centre is hot, edges are saucy. Marginally faster than the Panasonic thanks to the extra 100W, identical quality of result.

Microwave popcorn without burning a single kernel. Popcorn preset at 100g. Bag is inflated, six unpopped kernels, no scorch marks on the bag. Slightly worse than the Panasonic and Breville, noticeably better than the Samsung.

The reliability picture

This is where the Sharp loses to the Panasonic. ProductReview has a cluster of failure reports for the R395EST at the 20 to 29 month mark, mostly door-switch failures and magnetron deaths. The sample size is not huge (maybe 40 reviews mentioning failures), but it is enough of a pattern to take seriously. Combine that with the 12-month warranty and you have a microwave that might statistically outlast its warranty by 8-12 months and then start asking for money.

Sharp Australian service is real but thin. Two main service centres (Sydney and Melbourne), parts shipped from there to the rest of the country. Repair turnaround realistically is 4 to 5 weeks for a magnetron, versus 2 to 3 weeks for Panasonic. Factor that in if you do not have a backup cooking option.

Who it is for

People who want inverter technology for less than the Panasonic charges and who are willing to lean on Australian Consumer Law if things go wrong. Anyone who needs genuine high-wattage microwave output (busy kitchens, food prep, large family reheats). People with square or rectangular cookware. Skip this if you want the longest warranty in the category (that is the Samsung) or the strongest track record (that is the Panasonic).

Your rights under Australian Consumer Law: At $329 to $399, the R395EST sits in the mid-range tier and a reasonable consumer would expect 5 to 7 years of usable service from an inverter microwave at that money. Sharp's 12-month manufacturer warranty is the floor and it is deliberately short; the ACL expectation is the meaningful one. If the magnetron fails at 22 months (which the ProductReview failure cluster suggests is a real risk), if the door switch gives up at 18 months, if the inverter board dies at three years, each of those is a consumer guarantee claim. Take it back to the retailer (Harvey Norman, The Good Guys, Appliances Online, Bing Lee, whoever sold it to you), bring the receipt, explain the fault, and ask for repair, replacement or refund. The retailer carries the ACL obligation first, not Sharp. Do not let them palm you off to Sharp's warranty line without a fight.
