Mini Bubble Spirit Levels 30x9mm Spirit Level Bubble Measuring Instruments Layout Tools

These are very small and work very well. I keep a couple in my edc kit.

I added one of these to my front rifle rest, to check rough level while setting up. Plop down the rest, check, add the rifle and rear bag and then adjust with level attached to the rifle.

I only got 3 in the package I received. I know many reviews say it should be 6. 3 is not worth $7. These levels are really small and difficult to read against white objects and the tape is impossible to separate from the backing. Sending them back!

I bought these for my camera AND for my garage door. I used double sided tape and put one on each of the electric eyes. Once in a while they get knocked out of level when I move my garbage cans in and out of the garage.

I think it costs more than it should have. I believe that in the description it said that the "stick on" part didn't actually stick on.It wasn't leveled perfectly but you kind of eye ball it. It's small and compact. It's nothing too special. I think it is definitely overpriced for what it is but I was in a nick of time. I personally wouldn't purchase it again solely for the price and it not being as accurate as I would like it as well as it not able to stick on things without making another purchase outside of this.Good luck with your decision making.

Nice markings and steady bubble. This will not mount perfect on every drill but worked for me

I put it in a vice and filed on it with a coarse file until each level fell out. (They are NOT glued into the case.) Then I epoxied them to tripods.

I measured the accuracy with a digital meter and got about +/- 0.1 degrees for the large bubble, if one get the bubble centered well. It was also repeatable. The small bubble is much more, but did not measure that.
