Eufy Baby Monitor E21 review: buy or skip?

What the Eufy Baby Monitor E21 does well

The headline: wi-Fi monitor with local storage and no fees. Key specs: Connection: Wi-Fi; Video: 2K; Two-way audio: Yes; Subscription: None. In our list it is the pick for: no subscription Wi-Fi. It usually sells for $129–$159.

Cry detection alerts work without a plan.

The trade-offs

Good: no fees, 2K video, cry detection, pan and tilt. Not so good: app only, wi-Fi dependent. Read the skip-if line before you order: skip it if you need a dedicated screen.

What to buy instead

Instead, consider the Eufy SpaceView Pro ($139–$169): pan-and-tilt local monitor with a big screen. Better if you want a cheap, private monitor with pan and tilt.

Instead, consider the Infant Optics DXR-8 PRO ($179–$199): private, reliable monitor with interchangeable lenses. Better if you want a private monitor that never touches the internet.

Instead, consider the Nanit Plus ($199–$249): overhead camera with sleep tracking. Better if you want sleep analytics.

Before you buy

Wi-Fi monitors let you watch from anywhere; non-Wi-Fi monitors are more private. Night vision and two-way audio matter most. Breathing and sleep tracking are extras, not medical devices.

US buyer tip

Choose a monitor with encryption and two-factor login if it connects to Wi-Fi.

Prices on Amazon.com move in a pattern. The deepest cuts land on Prime Day in July, Prime Big Deal Days in October and the Black Friday to Cyber Monday week, with smaller drops around Presidents Day, Memorial Day, the Fourth of July and back-to-school. Judge a deal against the usual price we show, never against the crossed-out list price.

Order from Amazon itself or the brand's official storefront so the US manufacturer warranty applies, keep your order confirmation and register the product with the brand. Most items can be returned within 30 days, and holiday purchases often get an extended return window into January.
