I've covered every single Amazon AU Mid-Year Sale and these are the 7 deals I'd buy with my own money

Save AU$46.95

I've been using this ergonomic vertical mouse since its launch and I can't do without it. I had the Logitech MX Vertical prior to that and it was too large for my small mitts, but the Lift is perfect. It's helped me maintain a better posture, thus reducing aches along the wrist, shoulder and shoulder blade. While I've seen the Black colourway drop as low as AU$68 previously, it's still worth considering even this price.

I'm a Bose fan (and the Bose QC Ultra Headphones are down to their lowest price yet of AU$399.95), but I can't deny that Sennheiser's fourth-generation wireless over-ear cans are also fantastic. With very good active noise-cancellation, 60-hours of battery life and excellent sound quality, there are few pairs that can compete with the Momentum 4, particularly at this discounted price point. While their plain design may not appeal to some people (like yours truly), this better-than-half-price discount is worth considering if you want one of the best headphones in Australia. Just be sure to check the coupon box on the listing page.

I'm no elite athlete, but I must admit I'm beginning to get a little disillusioned by my Apple Watch. I've taken to wearing a smart ring recently, but the plethora of health and fitness metrics that Garmin's best wearables offer go even further, and unlike the Apple alternative, Garmin supports Android devices, so you don't have to be an iPhone user to take full advantage of this wearable. With a brilliant tough design, excellent GPS tracking, useful training tools and an epic battery life, my colleagues proudly handed this watch an Editor's Choice seal of approval in our Garmin Instinct 2 review. If you're OK with the black colour scheme and standard (45mm) size, this is one of the better Garmin smartwatch deals going.

DJI's answer to GoPro, the Osmo Action 4 is a great action cam that benefits from a superior sensor over its predecessor, and that's despite now being succeeded by the gen 5 model. With horizon balance, better low-light performance than any other action camera and a noise-cancelling 3-mic system, this model is one to consider if you're an adrenaline junkie. Plus it's cheaper than it was last Boxing Day, and only AU$4 more than the lowest we have seen on Amazon.

Save AU$700

I've tested this robot vacuum myself and I can't recommend it highly enough, even at full price. It does so much and, does it well, better than some more expensive models, that I think it's the best-value all-in-one robovac you can get. And this massive discount makes it more so. It will vacuum, mop, empty its own bin, wash its mop pads, then dry them with hot air as well. All you have to do is occasionally fill it with clean water and empty out the dirty stuff.

Ever wished you could cook with steam in your air fryer? Now you can with this Philips two-drawer air fryer. And I've tested it myself. In my Philips 5000 Series Dual Basket XXL Air Fryer Steam review, I said that it cooks everything really well, although there are some caveats to keep in mind when it comes to the use of steam. Still, it's absolutely worth the investment if you want to upgrade from an old air fryer to something more versatile.

Save AU$250

This is one item that's on my wish list. I wish I had picked it up when it was a touch cheaper during Black Friday, but I held off – I'm seriously considering biting the bullet now. It would be a treat for my hair that gets blow-dried nearly every day. It's Dyson's "most intelligent" hairdryer, designed to dry your hair faster and without the possibility of heat damage thanks to its new Scalp Protect mode.
