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

These fit just right on the handle for my iPhone. I use the handle especially while taking scenic photos while sightseeing, when I want the horizon to be level. The handle is also useful to minimize accidentally changing photo settings. The level and the handle work well together.

Accurate and easy to use. Great value for the money . Easy to attach to whatever you need it for . Functions great.

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

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 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 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.

This is my second set of these. I had to return the first set because they showed up with one of them out of fluid in the level. For some odd reason they wanted them shipped back instead of just letting me throw them out. The second set finally showed and I attached them (or tried to) to my drill and impact driver. They don't stay on. Any bump at all knocks them straight off. Whatever slippery material they have on the back makes the double sided tape not adhere well. The times when I had been able to keep them on long enough to check level while drilling made it clear you can't even make out the bubble while you're using this on a drill. Maybe they would work better for some other purpose, but not for what I needed them for. I will continue to search for a good level to attach to the drill. I would not recommend these if that is what you are after.
