6Pcs Small Bubble Level 10x10x29mm Mini Square Spirit Level Picture Hanging Levels Mark Measuring Instruments Layout Tools

They work great, no magnets so your gpu stays safe, I recommend your line a few so you get the most accurate measurements, as I did with my moster ASUS TUFF 5080

Perfect. I use them to set on top of frames when hanging them, and to place in different spots on the table when doing epoxy to ensure the surface is level.

These have really come in handy when hanging pictures in my room!

On a poor quality reference surface (aka my desk) all 6 levels show it to be flat within a margin of error. Most of the levels disagree on exactly where perfectly level is. Upon inspection with calipers all of the levels are slightly tapered (0.1-0.2mm over 29mm - less than 0.4 degrees)... and yet they all show more or less level. Each side is just a little bit different. Each level is just a little bit different from it's companions. That having been said, the only thing about these that annoys me is that the bubbles are all different sizes.Are they good enough to use on a uranium enrichment centrifuge? Not even close. For most everything else, they're probably good enough.

Hanging multiple Mixtiles or creating a fun gallery wall? Then these are a must-have! They made the process so much easier, allowing me to use these handy levels on several picture frames simultaneously as I arranged them on the wall.

Works great for my home made leveling board.

I love the fact that these came in a pack of six. Because I obsess over my pictures peeing straight and I found that I use them for more than that. And if I have just one I can't find it. They are very light and they're very accurate with a good quality for being such small pieces. I was thrilled because I never ever need to look for my leveler because I know I have one always ready to use. They are so handy and I highly recommend.

Nice
