We've picked out the best space tech Prime Day deals still available as star projectors, drones, model rockets and Lego sets are still discounted.

The 51mm model, in particular, is available for just $609, having previously been marked at $1,099 which is a staggering 45% off. This deal is available in all sizes (42, 45, and 51mm) but the biggest discounts are on the biggest size.

And while the SmartCard was built for wallets, people use it in clever ways: tucked in passports, in luggage, even clipped to pet carriers.

Today is the last day of Amazon Prime Day, which means it's your last chance to stock up on all of the household essentials that you use every single day.

Right now, the Roborock Q7 M5+ is on sale on Amazon for $249, down from $429 (42% off): This is the lowest price ever, just after Prime Day and the deal is open to everyone, not only Prime members.
