A lot smaller than i assumed, need to check the size in the description next time, these guys are 6mm, you could stand 6 of em on the flat side of a XT60 connector

Think they will be useful, not expensive and I can dot them onto the board that i use for leveling my quad and balancing props.

The quality is pretty lousy though, the backs are not flat, so laying them all out straight out of the package and they all show a different levels, im figuring i will need to have at them with sandpaper to get them flat

If you want some cheap light leveling dots and don't mind some sanding to get em right, these are a good deal

Unfortunately, they're completely useless.
5 come in a package.
- 2 have an angled bottom plate (the white part), so they will never indicated the right angle.

- 2 have the bottom plate so far out that the epoxy and metal ball make it wobble all over the place.

- One is straight. And that one has a crack in the clear plastic.

In other words, out of 5, 5 are unusable.
Good idea, horrible quality.

These are really small and tiny. You might want to stick one on your heli or quad to make sure it's level for on the field calibration or something. However, they have two flaws: first of all, they're not self-sticking so you'll have to glue them on yourself. And the second - more serious flaw is that the bottom is NOT flat! The bottom has a drop of hard transparent glue or plastic, so obviously these don't work out of the box. They just kind of wobble on a flat surface, so the readings are way off. So you'd ether have to sand off the bottom, or just glue it in place with some epoxy or hot glue and correct it's position by hand before the glue dries. On the other hand they're not that expensive, so it's a pretty good deal if you have no problem with some handiwork.
