Relative zero is the feature; absolute angle rarely is · review
A MEMS-based angle gauge stating ± 0.2° over 0–90°, in a splash-proof aluminum housing with all four faces usable as a measuring reference.
What the figures leave us with The one to buy at this price. A published figure, an aluminum body, and four faces you can put down on.
Thirteen euros, and the specification that the tool next to it omits.
MEMS technology reaching an accuracy of ± 0.2°, with four sides usable as a measuring reference, over a range of 0–90°. A powerful magnetic base stated to hold reliably on metal profiles, pipes and saw blades. A large LCD with automatic backlight and a data-hold function. A high-quality aluminum housing, stated as splash-protected and robust for construction use.
An angle gauge is often placed where it cannot be read — under a saw table, inside a frame, on the far face of a beam. Hold freezes the reading so the tool can be taken out and looked at. Without it, half the measurements a gauge is bought for cannot be taken at all.
A strong base on a steel section is what turns this into a hands-free instrument. On aluminum, stainless of the wrong grade, or thin sheet, the magnet does far less — and the tool becomes something you have to hold still, which is exactly when a hold function matters.
Catalogued and unsold: the American Amazon shop lists the reference with nobody behind it.

A micro-machined accelerometer used as the tilt sensor. Mcbazel states MEMS technology reaching ± 0.2°. It is the standard technology in this class of tool.
A gauge with one reference face has to be placed a particular way up. With four, it can be laid on whichever face fits the work, which on a bracket or inside a frame is often the only face available.
For setting blades, brackets and mitres, yes. For measuring a slope that passes through the vertical, the 4 × 90° gauges here read continuously through all four quadrants.

The value pick: a published figure, a metal housing and four reference faces for thirteen euros.
Amazon reports what buyers took in the month before this page was last checked: at least 50.
The figure is a floor, rounded by Amazon, and read through Keepa — it says what buyers picked, not what a maker claims.

± 0.2° stated · 4 × 90° range · built-in magnets · 3.5 × 1.7 cm (1.4 × 0.7 in) display
A four-quadrant angle gauge stating ± 0.2°, aimed at relative angles between surfaces, with a magnetic base and a stated display size.
Best for: Comparing two surfaces to each other — the job an angle gauge actually does most often.
≈ $17
4 × 90° (360°) · four magnets · absolute and relative modes · backlit
A 360° angle gauge with four base magnets and both absolute and relative measuring modes — the second mode being the one most angle work actually needs.
Best for: Work that alternates between absolute slopes and relative angles without changing tools.
0–90° and 0–180° · magnetic base · V-groove for pipe and conduit
A trade angle gauge with dual 0–90° and 0–180° ranges and a V-groove machined around the base, so it sits on pipe and conduit instead of rocking on them.
Best for: Pipe and conduit bending, where the tool has to sit on a cylinder and stay there.
