The Starrett 135A pocket level is a 2-1/2" long spirit level with a single vial for determining horizontal plane and smooth, convex ends for fitting in a pocket. The vial is made of glass to resist scratching and provide clear readings, and has a sensitivity of 17 to 21 minutes. The level has a hexagonal brass body with a satin nickel-plated finish that resists corrosion. Levels are used in the building trades, engineering, surveying, and metalworking, among other applications.
Levels are instruments that are used to determine the true horizontal or vertical plane of a surface. The most common type of level is the spirit level, or bubble level. Spirit levels have a liquid-filled, bowed tube (also called a vial) with a bubble that moves when slight adjustments are made to the level. When the bubble settles between marked points on the vial, it indicates that a surface is horizontally or vertically straight. Levels can have one or more vials to determine the horizontal plane, the vertical plane, or various points between, such as a 45-degree angle, simultaneously. Some levels include a laser line indicator that projects a horizontal or vertical beam on a surface. Bullseye levels, or surface levels, are circular, flat-bottomed spirit levels that determine whether a surface plane is level. Machinists’ levels are made of metal and have surfaces designed specifically for rugged use in a machine shop or tool room. Levels can range from highly-complex and accurate machines, such as those used in the surveying and construction industry, to precision instruments used in carpentry and other building trades, to simple, pocket-sized devices for do-it-yourself projects.
The L.S. Starrett Company manufactures precision measuring tools, metrology and testing equipment, and saw blade products. The company, founded in 1880, is headquartered in Athol, MA.

I use this level to mount my scope on my rifle. It is much more exact than the cheaper gun models.Very small with many uses.

Let me preface my review with this info - I have been a trade skill machinist for over 12 years now, I’ve had more than my fair share of handling Starrett, Mitutoyo, etc measuring instruments and levels.1st time using this level the end cap fell off for no rhyme or reason into my CnC machine, never to be found again. That’s 1st pic2nd time using said level, it was dropped from hip height and shattered the sight glass. While obviously not supposed to drop these things, but when working in machines or confined spaces, accidents happen.I am truthfully very surprised and upset with the complete lack of quality this Starrett level has. For something that is 40+ dollars for a simple 2” level, I don’t believe I will ever be buying Starrett name brand instruments for any of my tools going forward. Wanted to give Starrett a chance as I’m a mitutoyo guy, personally, and have seen some of my co-workers using them. Needless to say, unsatisfactory and lesson learned.

It's a real Starett item, one that was designed before they SOLD OUT to the 1%. Still great quality.

Works great. If you have a use for a small precision level, this is a great choice.

Comme vu dans les précédents commentaires il y a l’air d’avoir un lot de niveau Starret qui n’est pas fonctionnel.J’ai commandé une première fois ce modèle et après test il s’avère que les deux lignes indiquant le niveau ne sont pas équidistantes de la barre centrale, ce qui fausse toutes lectures.Après échange, le second que j’ai reçu était parfaitement calibré.Très bon niveau donc mais vérifiez bien à la réception qu’il est fonctionnel.

Ich benutze die Waagen zum Ausrichten von Zielfernrohrmontagen. Bei mir gibt es nichts zu meckern.Schnelle Lieferung und beide Wasserwaagen sind genau und präzise. Für meinen Zweck Ideal. Die Sola GO! magnetic ist ähnlich präzise. Deutlich besser als etliche Präzisionslibellen. Ich kann sie nur weiter empfehlen.Sie ist auch nicht zu empfindlich. Das Ausrichten geht schnell mit ihr. Sie ist auch schön schmal.
