Verdict
The Meswao MES-B3 or azamp MES-B3 is a special tablet: a display in 16:9 format is rare and then with 15.6 inches, that is almost unique. The large display has its advantages, especially when watching videos, when the entire screen area is utilised. Streaming in 1440p on YouTube works smoothly.
It's a shame that the manufacturer hasn't taken care of Widevine licensing, then you could also enjoy HD content from other streaming providers. When it comes to security updates, the manufacturer talks about an update guarantee until 2027, but this is not realised in practice: The security patches on our test device are already over a year old.
You shouldn't expect much in terms of cameras and speakers. The screen is also not particularly bright, but is usually sufficient for indoor use. At least there is no PWM flickering when the brightness is low.
The runtimes are okay, but charging takes a long time. The performance is sufficient, but you have to put up with occasional stutters and waiting times.
Overall, the azamp / Meswao MES-B3 focuses very much on its highlight, the large screen. If this is sufficient as an argument and you can live with the disadvantages mentioned, then you can definitely have fun with the tablet in everyday life.

Specifications
Case and equipment – Heavy, but stable
A tablet weighing over 1.1 kilograms is rarely carried around with you. In return, the MES-B3 offers a huge 15.6-inch screen in 16:9 format. The width of the screen edge is medium.
The back is slightly roughened and available in grey, black or white. The tablet is very stable for its size and can hardly be twisted. Pressure quickly reaches the liquid crystal and forms visible waves.
With 6 GB RAM and 128 GB mass storage, the tablet is sparcely equipped for its price range. The memory can be expanded via a microSD reader, although it does not transfer data very quickly.

Communication and operation – Tablet with WiFi 5
WiFi 5 is the fastest WiFi standard that the tablet comes with. The expected data rates of around 300 MBit/s are achieved quite stably.
There is no variant with 5G reception and no satellite positioning.
The touchscreen works reasonably accurately, although you have to repeat a command from time to time. The buttons at the top of the tablet for standby and volume are a little small, but are easy to find. Unlocking the tablet via fingerprint sensor or facial recognition is not possible.

Software and sustainability – The update promise sounds good, but...
Android 14 is pre-installed on the tablet. The security patches could also do with a new version, as they date back to 2024.
This is a shame, as the manufacturer actually promises updates until 2027, but these are apparently not being provided.
CO2-neutral production via emissions offsetting is promised, but this cannot be verified. Other sustainability efforts are not recognisable.
Cameras - Hardly useful
There is a 32-megapixel sensor at the back, which serves as the main camera. However, this is only a makeshift, taking coarse and grainy photos that lack dynamism and sharpness. They are also taken in 16:9 format by default, which is rather unusual for still images.
Videos can be recorded in a maximum of 1,440p at 30 fps. The autofocus and brightness correction are a little slow, but overall the videos are OK.
The front camera takes passable selfies, but these are also a little grainy.

Choose a scene and navigate within the first image. One click changes the position on touchscreens. One click on the zoomed-in image opens the original in a new window. The first image shows the scaled photograph of the test device.

Display – Large but dim display
The large screen is certainly the highlight of the azamp MES-B3 or Meswao MES-B3. At 15.6 inches, it is indeed enormous for a tablet and, with its 16:9 format, offers ideal conditions for watching videos, as most videos on the Internet are available in this format.
However, there is one problem: the MES-B3 does not have Widevine L1 certification and is therefore not suitable for copy-protected content. Streaming on Netflix and co. will therefore only work in SD.
The maximum brightness of the screen is not particularly high at just under 300 cd/m², but it is sufficient for indoor use. While greyscales are only displayed with a slight yellow tint, there are strong colour deviations, especially in blue tones and strong colours: The picture appears very dull overall.
The screen comes without PWM flickering.

Performance, emissions and battery life – Enough power for 1440p
Thanks to the MediaTek Helio G99, the giant tablet delivers mid-range power. The performance is usually sufficient for everyday use. Streaming via YouTube even works smoothly with a resolution of 1,440p. Unfortunately, the eMMC memory is very slow and delays loading times and copying processes.
The tablet barely heats up under prolonged load and the SoC only minimally reduces its performance.
The large tablet comes with four speakers. However, these are not really loud and are very treble-heavy. It's more fun to connect external speakers or loudspeakers. This can be done via USB or wirelessly via Bluetooth. A large selection of wireless audio codecs is available so that you can listen to music in good quality.
The 12,000 mAh battery enables a runtime of up to 17:35 minutes in our WLAN test. This is OK, but not record-breaking; the large screen probably limits the runtime here. Charging takes just under 6 hours at maximum, as only 15 watts of charging power is available.

Notebookcheck overall rating
If you absolutely need a huge screen, then the MES-B3 is almost unrivalled.
However, there are some hard pills to swallow, such as the completely outdated security patches.
