6 pcs Bubble Spirit Level, 32x7mm Circular Level Bubble for RV, Travel Trailer, Tripod, Phonograph, Turntable

Excellent bubble product!

I purchased this set of 6 levels for "initial" leveling of my new 3D printer. Starting off with a level surface is important for any number of hobbies and in my case the immediate use was for setting up the rough level of a new 3D printer. These levels have a center target that gets you within about 1% of level and are easy to just set down on a print bed or frame for quick leveling. They are inexpensive and easy to see and use. While they do not have "any" type of adhesion this is perhaps better and faster in moving the level to various places around your project and makes it easy to slide them along an X or Y axis. The levels seem well made for the intended purpose and my intention was to actually attach these to the four corners of my printer on a permanent basis but I have not looked into how I would do that (glue, double stick tape, etc. ?) so in that regard perhaps a little disappointing in function. I would also suggest this for resin projects and wood projects as well.

This bubble levels are used in our manlift so that we can make sure all four legs are level. They work like a charm.I’m

Never thought I would use this on my drill and impact but how did I ever get something straight with out them . Got to have these for drill and driver

Set up a recently purchased turntable, dropped one of these on it and it was dead on level, so tried a second one and it also was dead on. All seemed to be well made.

Good price but i just compared a few of the levels to each other and they don't agree on my very flat desktop

They are large enough for an old man like me to read. I put one on a magnet to hold it to the bar of my chainsaw. I make the stumps perfectly level and use them for plant stands. I also hot glued one to my drill to help making vertical holes. I would buy them again.

Got them for scope mounting,they should be perfect.thin enough to fit under scope on pic rail.

Simple "device". does the job designed to do. Good relation between price paid and quality.

Only 3 out of the 6 were accurate. Those worked well for fitting rifle scopes.

5out of 6 have very good accuracy, I was anticipating 50% to be of dubious accuracy but am pleasantly surprised. I have smaller bubble levels but these are marked far better and of a good size for most situations requiring multiple levels. Good value for money for what you get

I wanted an easy way to see just how level my 3D printer was, and these self-adhesive bubble indictors did that perfectly and cost-effectively.

Not all of these are entirely accurate, 3 of mine were good, 1 not too bad and 2 a bit too far off. Lucky I took the time to check them before gluing them into my project(smart telescope mount).... Still, they are cheap and providing you are willing to check them and only use what's good they still work out not bad value(well providing most are accurate). I only needed 2 anyway so not a big issue for me but worth bearing in mind before you buy!!
