10pcs Bubble Spirit Level Degree Mark, 10x6mm Mini Circular Bullseye Level Inclinometers Use for Tripod, Phonograph, Turntable

I read the reviews before I bought these. Some people were complaining because they were so small. That was the whole purpose of having small levels - so that they would be small. These do exactly what they’re supposed to do and they work perfectly well. I’m quite happy with them, and they are working perfectly for my needs

FYI these are approx the size of a pencil eraser. Just what I wanted but they are quite small if that's what you are looking for

Bubble sizes differ slightly. Used on drill to help keep plumb with hot glue as no surface of drill is in line with drill blt. Working well.

I purchased the 12mm size and they are too small for what I wanted, my mistake. I will have to think of another use for these.I tested them out on a precision leveled surface plate and some of them are off a little and will need some careful sanding to correct, not a big deal and it's what I expected.

I was looking to add a level to a Grizzly BR Shooting Rest. Theses Bubble levels work very well. I had limited area to work with.

These were just what I needed for the restoration of a Bogen tripod. It fit perfectly. I only needed one, but I was happy to find these at all anywhere.

I used one to help keep my tripod level. Videoing church services outside I needed an aid to shoot level on a slight incline. The size of the level allowed me to locate it on the only place available on the tripod. I used a 3M double sided pad to attach it to the tripod since it comes without an type of adhesive. It works for my purpose.

I lost one of these levels in one of my tripod leveling head, making the head totally useless. It is not inexpensive to replace the head, so I wanted to find an alternative solution. Unfortunately, I was able to find this bubble spirit level that fits perfectly in the vacant spot of the leveling head. Now it is back in business, saving me a lot of money.
