1 / 770mai M310 Plus 4K Front Dash Cam, 2160p
The 70mai M310 Plus 4K is a compact, screen-free front dash cam with Wi-Fi, app access and listed 2160p video capture. It is suited to drivers who want to review and download footage on a phone, but parking monitoring and time-lapse need a separately sold hardwire kit.
At a glance
- Screen-free, compact design with manual 360° rotation and app options for video flip and mirror mode.
- Listing claims 3840×2160P recording and a 140° field of view. These are manufacturer specifications, not independently verified measurements.
- 2.4G Wi-Fi and the 70mai app are described for viewing live footage and downloading recordings to a phone.
- Loop recording overwrites the oldest files when the card is full. The listing says microSD cards from 16GB to 256GB are supported and recommends U1 or higher.
- Emergency recording uses 1–3 min loop segments, with collision-triggered footage described as up to 210 seconds.
- Parking monitoring and time-lapse require a separately sold hardwire kit. The listing says time-lapse records at 1 frame per second.

What to know before buying
Listing details to confirm
The product title and feature copy claim 4K and 3840×2160P, while the details field lists 2160p. These refer to the listing's resolution claim but do not independently establish performance. The title calls it a front dash cam, while feature copy says it can be rotated for front or rear windscreen mounting, so confirm intended camera positioning before purchase. The listed storage capacity is 256 GB, and feature copy describes this as the maximum supported microSD size, with cards not included.

Customer feedback describes clear footage, straightforward setup, compact size and phone downloads as positives, with some customers saying it works reliably for daily use. Those impressions align with the listed 2160p resolution, screen-free design and app access, though reviews do not verify those specifications. The overall rating distribution is mostly positive but includes a notable one-star share, so experiences are not uniformly favourable. The feedback supplied does not explain the reasons behind lower ratings.
