Beam-splitter glass costs light, and the reflection has to be controlled · review
NEEWER Basics X12B, 12 inches, 75 per cent transmission review
The only prompter on this shelf that publishes its mirror — 75 per cent transmission on a 12-inch beam splitter — and the only one that twice states what it cannot do.
The bottom line Seventy-five per cent transmission on a named beam splitter, an adjustable aperture, font-size control and a rigid case for 109 € — the only prompter here that publishes its mirror. It says twice that it is not for shooting on a phone, and the remote arrives without its battery.
On the listing
Six bullets. An introduction to NEEWER BASICS as a value range focused on essential functions, with a note that it is not suitable for shooting with a smartphone; a prompter needing no setup, a flip-up platform and beam splitter keeping the lens centred with iPad, tablet and camera, named for presentations, online courses and tutorial recording, and not suitable as a monitor or for direct self-view; remote and app control through the RT113 remote (AAA battery not included) or the NEEWER Teleprompter app for iOS 11 and Android 6 or later, starting and pausing playback, adjusting scroll speed, turning pages and changing font size over Bluetooth; a clear 12-inch HD display whose specially coated beam-splitter glass has 75 per cent light transmission for clear text readable to 10 ft or 3 m, with an adjustable aperture reducing glare and the X14, X14 Pro, X14 II, X16 and X17 II named for anyone wanting a larger screen; a foldable, portable construction packing flat into a rigid carry case; and a repeat of that bullet adding that phones mounted on the prompter display text only and do not support photography or video.
Seventy-five per cent, published
The only mirror figure on this shelf. Three quarters of the light to the sensor, a quarter to the reader: about a third of a stop, known in advance instead of metered on the day.
A beam splitter, called a beam splitter
The word is the specification. A mirror reflects everything and shows the camera nothing; a splitter divides the light, and this is the page that says which it is.
An aperture that closes onto the lens
Adjustable rather than fixed, so a slim prime and a fat zoom both seal against stray light. Nothing else here adjusts.
Font size, from the remote
Speed and page turns are on every remote. Font size decides how far away the reader can stand, and it is on this one.
Two sentences about what it will not do
Not for shooting on a phone. Not a monitor, not for self-view. Stated in the first bullet and again in the last, which is more use than a specification that leaves it to be found out.
Availability
Between 109 € and 145 € on the German, French, Italian and Spanish Amazon stores when this page was last checked.
The American and British Amazon stores carry it too, priced in local currency. Those amounts are deliberately absent from the range above, which reads euro stores only.

What it does well, and what it gives up
Strengths
Seventy-five per cent transmission published — the only mirror figure on this shelf
An adjustable aperture, and font-size control from the app
A twelve-inch screen, a rigid case, and the larger models named for anyone who needs more
Compromises
It states twice that it is not for shooting with a smartphone
The remote’s AAA battery is not included
No weight and no folded size published
Specifications
Glass type
A BEAM SPLITTER, named as such in the second bullet, with a special coating described in the fourth. Naming it matters: a prompter needs a splitter rather than a mirror, and this is the page that uses the word
Stated ratio
PUBLISHED — 75 PER CENT LIGHT TRANSMISSION, in the fourth bullet, and it is the only such figure on this shelf. Seventy-five per cent to the camera leaves 25 per cent for the reader, which costs roughly a third of a stop of exposure and is the honest trade a prompter makes. Three other pages here leave the number out
Device sizes accommodated
Twelve inches, in the fourth bullet, for iPad, tablet and camera — and the fifth bullet does something unusual: it names the larger models in the range (X14, X14 Pro, X14 II, X16, X17 II) for anyone who needs a bigger screen. Text is readable to 10 ft or 3 m
Lens opening
An ADJUSTABLE APERTURE, in the fourth bullet, credited with reducing glare — the only adjustable opening on this shelf. A fixed hole either fits the lens or lets light past it; an adjustable one closes down onto the barrel
Hood design
The adjustable aperture is the page’s answer to stray light. No separate shroud is described
Mounting arrangement
A flip-up platform and beam splitter keeping the lens centred, in the second bullet, named for presentations, online courses and tutorials
Assembly
No setup, per the second bullet: the structure folds flat into a rigid carry case for storage and transport, in aluminium alloy. Described twice, in the fifth and sixth bullets
Software
The RT113 remote — AAA battery NOT included — or the NEEWER Teleprompter app for iOS 11 and Android 6 or later, controlling play and pause, scroll speed, page turns and FONT SIZE. Font size is the control the other pages omit, and it is the one that decides how far the reader can stand

What people ask before they commit
What does 75 per cent transmission cost the image?
About a third of a stop. Three quarters of the light reaches the sensor and a quarter is reflected to the reader, which is a small and predictable penalty — and knowing it is the point. Three other prompters on this shelf publish no ratio, so their loss is discovered by metering through the glass on the day.
Why does the page say twice that it is not for smartphone shooting?
Because the frame is built for a camera lens. The first bullet says it is not suitable for shooting with a smartphone and the sixth repeats that a phone on the prompter is for displaying text only. That is a limit stated plainly rather than left for a return — and the honest reading is that this is a prompter for a camera, with a tablet as the script.
What is font-size control worth?
Distance. The third bullet lists font size alongside speed and page turns, and font size is what decides whether the text is readable from 1 m or from 3. On a 12-inch screen at 3 m the words have to be large, which means fewer per line — and being able to change that from the remote is what makes the same setup work for a close shot and a wide one.

Best for: A bag with several lenses and a full-size tablet, shooting both landscape and vertical.
A BUILT-IN DISPLAY: no tablet or smartphone required, alone on this shelf · glass type not named and NO split ratio published · device sizes not applicable — the screen is part of the unit · lens opening described only as supporting more cameras than any other, "even the widest lenses" · hood not described · mounting arrangement not described · setup by plugging the camera in, driven from a PC or Mac desktop with no third-party mobile app · the Camera Hub app customises text and chat appearance, works with Stream Deck · DisplayLink software required on Mac, DisplayLink Presenter on Android, both free downloads
Two hundred and forty-eight euros for the only prompter here with its own screen — driven from a desktop, showing a script or a live Twitch chat while you look down the lens.
Best for: A desk-based streamer or presenter on a PC or Mac who wants eye contact on calls and a chat window under the lens.
A REFLECTION SCREEN of 28 by 19 cm, called a TV-studio size · no split ratio published · takes smartphones, tablets, still cameras and video cameras · lens opening not dimensioned · hood not described · fits all tripods, per the third bullet · aluminium, 600 g · text readable at 2 to 3 m · a FOOT PEDAL remote plus the Leeventi "voice-teleprompter" software with a ONE-YEAR LICENCE
Thirty-five euros for a 28 by 19 cm aluminium prompter at 600 g, with a foot pedal and a one-year software licence — and no split ratio anywhere on the page.
Best for: A tripod-mounted phone or camera where a foot pedal matters more than a published mirror specification.
