Our top pick

If you're looking to add an extra set of eyes to your home for security, the TP-Link Tapo MagCam offers sharp 2K video and a year-long battery life at a price that won't break the bank. Not to mention, it's on sale for it's lowest price on record as of May 16. While we haven't had a chance to test it ourselves, our friends at PCMag (which is owned by Mashable's publisher, ZiffDavis) have done the honor and awarded it a 4.5 outstanding rating. "It's an excellent value for a battery-powered camera that offers color night vision, built-in spotlights, local and cloud storage options, free intelligent alerts, voice control, and many other features," the review states, all of which earned the camera an Editors' Choice award. Usually $119.99, you can snag the TP-Link Tapo MagCam on sale for just $79.99 at Amazon with the on-page coupon.

Shark's SmoothStyle launched last summer and looks and acts like a fancier Revlon One-Step. It's basically a round hot air brush with some extra features. You can start with your hair wet and use the three preset air temperatures to dry and style your hair in one go without frying it. Once it's dry, you'll use the SmoothStyle like a thermal brush, with one preset heated smoothing comb setting. The comb itself has ceramic-coated plates to keep it from damaging your locks. Usually, it would run you $100, but as of May 16, it's on sale for just $79.99 at Amazon. That's 20% in savings and only the second time its dropped to this low of a price.

Looking for a pair of noise-cancelling earbuds that won't break the bank? Anker's Soundcore Liberty 4s offer premium features like spatial audio, ACAA 3.0 technology for clear and crisp sound, personalized ANC, and an in-ear heart rate sensor to detect your heart rate as you listen throughout the day, all for just $79.99 as of May 16. That's $50 off the usual cost and the lowest price on record since their release at the end of 2022. They come with CloudComfort eartips to ensure listening for up to 28 hours (with the included charging case) remains comfortable the whole time.

Although it's not the lowest price we've seen, 50% off any Roomba is reason to sound the alarm. The Roomba j7 is one of the most solid Roombas (and robot vacuums in general) you could bring home, thanks to its small obstacle avoidance feature. The j series Roombas will steer clear of smaller obstacles in your home, like phone charging cables, socks, and pet waste — a capability that Mashable Senior Shopping Reporter Leah Stodart found to be an "absolute game-changer." While it doesn't sport on-board mopping or self-emptying capabilities, we're more willing to forgive since it's on sale for only $299.99. That's $300 off its usual price and about $37 shy of its all-time low.
