I am a classical musician (violist) with 20 years of professional experience in orchestra and chamber music. For many years, I have been advising colleagues, students, and fellow musicians in the choice of their tablet.
Along with the many positives of using tablets, I’ve also seen the negatives: tablets crashing just before going on stage, batteries that don’t hold up during long rehearsal days, and missing page turner pedals in concert.
Meswao / Azamp MES-B3 (Pro): strengths and weaknesses
Verdict: a huge screen for little money, with compromises
The Meswao B3 Pro is a 15.6-inch Android tablet with a huge screen for little money. It is the August 2025 update of the 2024 MES-B3 (also sold as Azamp and Hoogee); the older version is still sold as the B3 Basic. The hands-on large-screens.com review found a unique size at a low price, but a dim, low-resolution screen, a slow chip and a high weight.
Screen: 28 % larger than the iPad Pro, but dim
The IPS screen uses the 16:9 format, even wider than 16:10 and made for videos; its area is 28 % larger than the screen of the 13-inch iPad Pro. At 1920 × 1080 (141 ppi), text is not very sharp. Notebookcheck measured 296 nits on the original MES-B3: enough indoors, too dim in the sun, and the glossy glass reflects lamps. There is no PWM flicker.
Speed: Helio G99; now with Widevine L1 for HD streaming
The MediaTek Helio G99, an entry-level chip from 2022, is fine for video, the web and documents but slow in games. The B3 Pro has 8 GB of RAM, 256 GB of storage and a microSD slot. Meswao now ships it with Android 16, Google Play and Widevine L1 (HD on Netflix and Prime Video); the units reviewed in 2025 ran Android 14 and played these apps only in SD, and older stock may still do so. There is no update policy, and Notebookcheck found security patches over a year old.
Battery: 17.6 hours; very heavy at 1,085 g
Meswao sells an active pen and a folding Bluetooth keyboard with touchpad. The 12,000 mAh battery lasted 17.6 hours in Notebookcheck’s Wi-Fi test; it charges at 30 W. At 1,085 g (2.4 lb) and about 1 cm thick, the tablet is very heavy, and its four speakers sound thin (large-screens.com). It has one USB-C port and no headphone jack.
Pro and Basic versions, and the larger 16-inch rivals
In October 2026, Meswao sells the B3 Pro and a cheaper B3 Basic (6 GB / 128 GB, Android 14) in Europe and the US, both at low prices. Meswao’s 16-inch B5 and the Acer Iconia A16 are now larger.
Pros
- Huge 15.6-inch screen (28 % larger than the 13-inch iPad Pro)
- MicroSD card slot
- Stylus support (sold separately)
- Great price for its size
- Supports Google Mobile Services
Cons
- Low-resolution display and low brightness
- Slow processor
- No Widevine L1 on early units (HD streaming)
- Stylus not included
- No information on security updates and software support duration
Meswao MES-B3 Pro or a 16-inch tablet (Meswao B5, Acer Iconia A16)?
These three large, low-cost Android tablets have screens of 1920 × 1080 or 1920 × 1200 pixels, not very sharp at this size (about 140 ppi), and none has a published update policy. The 16-inch 16:10 screens are about as wide as the 15.6-inch 16:9 screen of the MES-B3 Pro, but about 11 % taller in landscape, with about 11 % more area.
- Choose the Meswao MES-B3 Pro if you want a tablet that has been reviewed: it is the only one of the three with a hands-on review on this site and an independent test (Notebookcheck, original MES-B3). It is the thickest (about 1 cm) and weighs 1,085 g.
- Choose the Meswao B5 for the largest screen with a keyboard and a pen: the same Helio G99 chip and the same optional keyboard with touchpad as the MES-B3 Pro, but 16 inches, 12 or 16 GB of RAM and Widevine L1 (according to Meswao); it is the heaviest (1,120 g), and no independent review exists yet.
- Choose the Acer Iconia A16 for videos: it is the lightest (980 g), has a built-in kickstand and a headphone jack, and is the cheapest; but its chip is slower, and it supports neither a pen nor a keyboard.
Performance
The Meswao MES-B3 (Pro) is powered by the relatively old MediaTek Helio G99 processor, released in 2022 and built on a 6 nm process. It is fine for streaming, web browsing, documents and casual games, but it is not made for demanding games, video editing or heavy multitasking. The same chip is used in 8 other tablets of our database, including the Meswao B5 / B5 Basic and the Meswao B4. Compared with other large tablets:
- The Apple M5 in the Apple iPad Pro 13″ (M5) is about 8 times faster.
- The Unisoc T7300 in the Alldocube iPlay 70 Max Pro is about 20 % faster.
- The Meswao MES-B3 (Pro) is about 30 % faster than the Acer Iconia A16 and its Allwinner A733.
Brightness
The screen of the Meswao MES-B3 (Pro) reaches 350 nits according to Meswao, which is enough indoors, but not for outdoor use in the summer (600 nits is the minimum). Notebookcheck measured 296 nits.
